FIRST ALERT Carbon Monoxide Detector, No Outlet Required, Battery Operated, CO400, White, 2 Count (Pack of 1) 2 Unnecessarily difficult to install campbe*** Battery compartment is very difficult to open re3quiring broken fingernails and a pliers and small screwdriver.. Instructions for opening on the installation sheet don't apply to this model. Also, why did they make the distance between the mounting screws different from their older model which I replaced? This necessitated drilling an additional mounting hole in the wall. Both the older and newer models were identical in size and so there was no reason to reconfigure the mounting screws. B00BMLIEOA US
Color Remover, 2 Ounce (Pack of 1) 3 Works, but open your windows first! Jenn*** I dyed a dress Kelly Green, and it turned this weird army green. Not a good color for me, so I thought I’d remove it. Bright side: it worked super well (using the stove top method), but the downside is that the smell set off every carbon monoxide detector in my house. I had the excellent exhaust fan running on max, not enough. B00PC5RXAI US

Google Nest Protect - Smoke Alarm - Smoke Detector and Carbon Monoxide Detector - Battery Operated , White - S3000BWES 5 Love it! Nicol*** I didn't think I could love a smoke alarm, but I love Nest. It was easy to install and I understood how the app and system worked in less than five minutes. Nest makes me want to test my smoke alarm! The design and human voice draws you in. I love the colored rings and the Pathlight feature. I have to refrain from pressing the button every time I walk by! B014KEPWS6 US
FIRST ALERT Dual-Power Plug-In Carbon Monoxide Detector with Battery Backup and Digital Display, CO615 , White, Pack of 3 5 Carbon Monoxide detector Sherma*** The first alert carbon monoxide is a great product.

You can order an extra adapter if you have Kiddie detectors and want to upgrade to First Alert without touching any bare wires or wire nuts. If you already have First Alert, these just plug in. B07ZHKFR85 US
Kidde Smoke Detector & Carbon Monoxide Detector Combo with 10-Year Battery,White 1 Twice Defective, 100% AVOID Sar*** First, this piece of trash was installed in my apartment and had to be replaced because it would go off for no reason. Then, the replacement went off just now, and the button would not work to shut it off. I took it by a window, still kept beeping. Took it OUTSIDE and it STILL. KEPT. BEEPING. Ultimately had to take it apart and switch it off from the inside. Couldn't even just remove the battery; it's not removable. Now my bed's soaked in pee because my poor dog got so nervous from the thing not shutting off. I didn't buy this myself, but now I certainly never will. B08DHDX3DT US
EXCEL TANKLESS GAS WATER HEATER Vent Free (LOW WATER PRESSURE STARTUP) 1.6 GPM PROPANE LPG 1 Update! Failure could have killed someone. Lance an*** Update: I hate to sound alarmist, but this heater, after functioning as described below for 3 years, failed by staying lit with no water flow. If one of our sons hadn’t been close enough to the unit to smell smoke and hear the creaking heat exchanger, acting quickly to turn off the fuel manually, it would have caused a fire or explosion. There’s no pressure relief valve or any way built in to tie a pressure sensor to the ignition circuit, and the haphazardly included thermal switch failed to shut the unit down. The initial fault was in the flow sensor. Whether the magnetic “float” is sticking in the inlet tube, or the reed switch is sticking “closed”, I can’t tell. In either case, the temperature switch bench tested good with a heat gun, but failed to open the circuit, even when damage was occurring, while installed and tested in fault condition several times. Excel used no conductive thermal paste between the tubing in the heat exchanger and the thermal switch, so I’m not surprised it never worked. Without a way to test the specific temperature sensitivity of the switch, there’s no way to tell if it would prevent fire or explosion, even if it were in good conductive contact. I emailed ExcelAmerica and they responded fairly quickly, demanding a picture of the unit, claiming they had too many versions of this model number to help me (Red Flag!). I sent photos, including the ID tag on the unit which leaves the serial number blank (stupid thing to do as a manufacturer). From that point on, I have gotten no response. If you take a chance on this junk, beware! Add your own safety switch to cut power to the fuel solenoid (which would void warranty or skirt Excel’s liability for their unsafe product) or add your own solenoid valve in-line. If you don’t understand what I’ve said here, look elsewhere for a UL and UPC listed heater and avoid the inevitability of a dangerous failure with this one. Original review a couple of months before failure, including some more general advice on living with tankless heaters: With generally cheaply made Chinese junk, I’ve learned not to discount others’ experience of defects and lousy customer service. That said, this heater has been great to us for the last three years using it in our full time residence. There is a learning curve to deal with: both from flow limitations and from temperature variation in use. We use it with a small diaphragm pump with a 2gal pressure tank which lets our pressure and flow vary quite a bit, as RVers may know. The resulting temperature instability isn’t really the fault of this unit, as much as a problem inherent to these systems. They’ll never behave like a big tank heater on city water. With patient, systematic experimentation, the controls (water flow and flame output) can dial in a very useable shower experience, but scalding and cold water slugs are part of the game. Even so, with care, we’ve used it safely with a bunch of kids of all ages, though built-in scald guards in modern pressure balance shower valves don’t work effectively with these units in variable pressure systems. Be careful! Dishes, tub filling, and laundry (hot) that demand more straightforward hot water are great! Add a mixing valve and behavior is persnickety. The ventless feature is great for us, as has been the automatic piezoelectric start. We never use the unit for more than 2 or so minutes at a time and not more than 4 gallons, so the runtime and exhaust gas volume is low in our case. Still, a carbon monoxide detector is highly recommended, even necessary in a closed space. I’m going to buy a second one for our other cabin. Here’s hoping I get the same performance and durability.

Kidde Smoke and Carbon Monoxide Detector, AA Battery-Powered, Wire-Free Interconnect, Voice Alerts, LED Status Light 85 dB Al 5 Simple and modern upgrade to older hard wired detectors. Micha*** I installed the Kidde smoke and carbon monoxide detector a few weeks ago and it’s been a modern upgrade from my older alarms. Setup was quick since it’s battery powered and wire free, I didn’t have to mess with electrical wiring or call anyone for help. The interconnect feature is really useful; when one alarm is triggered, the others sound too, which gives me piece of mind for the safety of my family. One thing I really like is the voice alert system. Instead of just hearing a loud beep and wondering what’s wrong, it clearly tells you whether it detected smoke or carbon monoxide. The 85 dB alarm is definitely loud enough to get your attention, and the LED status light makes it easy to check that everything is working properly. The unit feels well made and compact without looking bulky on the ceiling. Battery installation was simple, and I like not having to deal with hardwiring. The only pitfall to this setup is I have a total of 7 hardwired detectors to replace. Overall, this detector is reliable, easy to install, and offers excellent safety features for the price. Definitely worth buying if you want a dependable combo smoke and CO alarm. B0GGGH39SZ US
X-Sense Smoke & Carbon Monoxide Detector Combo, 10-Year Sealed Battery, Battery Powered (Not Hardwired), Model SC07, 3-Pack 5 Great Jarrod *** I left a similar review on the Wi-Fi connected version so I will keep this short and sweet. I wanted to have some 'dumb' detectors for my bedrooms and smart ones for each floor. I like that at a glance they look the same so you don't have a weird looking mish-mash. Easy to setup, all hardware was included. Nicely packaged. The feel solid and look good. Very satisfied so far, the only thing I can't speak to is if they will last 10 years or not. B00002N86A US

Kidde Intelligent Smoke & Carbon Monoxide Detector, Battery Powered, Combination Smoke & CO Alarm with Voice Alert 2 Didn't last longer than a year M*** Purchased this alarm for the convenience of a voice telling you exactly why the alarm is sounding. We've had the unit for almost exactly a year and it's now broken. Started going off in the middle of the night saying "fire!" and beeping. Would be great if there was fire but there's not. Tried blowing air in the unit and replacing batteries with no luck. Pretty disappointed that a 10 year unit is failing after one year. B00XV1RCRY US

First Alert BRK SC9120B-6 Hardwired Smoke and Carbon Monoxide Detector (CO) with Battery Backup. 6-Pack , White 1 New model SMICO100-AC does not fit in mounting bracket of SC9120B so bracket needs to be installed fra*** I ordered a BRK SC9120B0-6 CO & Smoke detector. What I ordered had an actual picture of the SC9120B detector but the company Electric Voltage out of LA, Cal sent me the upgraded model SMICO100-AC without asking me if I wanted the upgraded model. Functionally the new model works with the old model but they are not the same physically. The new model does not fit in the original mounting bracket so the bracket would have to be changed out and rewired. In addition the original model was about $53 more than the new model for the six that I ordered but Electric Voltage still charged me the price for the old model. I have complained to Amazon customer service but I have not gotten a resolution to the issue. B07ZHKFR85 US
Kidde Smoke Detector & Carbon Monoxide Detector Combo with 10-Year Battery,White 1 Brand new and CHIRPS Rosanne *** I bought this combo smoke detector and carbon monoxide detector and had it installed during my condo renovation by a professional contractor. A couple of days later, the unit was chirping. Thought that it was reset and working again, it chirped again the next day. The 30-day return time expired THE DAY BEFORE the problem appeared and Amazon won't take it back for a replacement. I have to deal with Kidde customer service. Either get another Kidde model or another brand. Defective! Either old battery or something else wrong with it. Too expensive to just throw away and eat the price loss. B09FXXXG95 US
Wireless Interconnected Combination Smoke and Carbon Monoxide Detector, 10-Year Battery Powered Fire and CO Alarm, SC06-W, 3-Pack 1 Why not UL certified? Stev*** Can the seller or manufacturer comment about lack of UL certification? I was eager to purchase the three-pack but they appear to not be not UL-certified. The seller says they meet UL requirements but that is different than being UL certified. These would not pass inspection since they've not truly been independent tested. I'm disappointed as I like the design better than Kidde or First Alert. But when it comes to smoke and CO quality and certification is more important than aesthetics. B0BZRBKS3M US

X-Sense Smoke & Carbon Monoxide Detector Combo, 10-Year Sealed Battery, Battery Powered (Not Hardwired), Model SC07, 3-Pack 4 Invalid Serial Number DAMAGED (Not for sale) - EDIT: X-Sense Resolved Issue Bobby *** EDIT: X-Sense emailed me after seeing my review. They replaced my smoke detectors free of charge. I'm still not sure if there's wrong with the original detectors, but it was nice that X-Sense sent me new ones just in case. ORIGINAL: I bought these smoke detectors in Nov 2024 and just got around to putting them up. Right out of the package everything seems fine. I installed them on my ceilings without issue. BUT after getting them up, I noticede this red sticker on the back of the outer package sleeve. "Invalid Serial Number DAMAGED (Not for sale)" Did X-Sense send me damaged or returned devices? I'm not sure if these should be returned or what. Very annoying after spending $100+ dollars on smoke detectors. B00002N86A US

Kidde Carbon Monoxide Detector, Plug-In with 9V Battery Backup, Digital Display, 85 dB Alarm, LED Status Light Indicators, 3r 3 So replaced it with another that is just like the first one Amazon C*** Got this as a replacement for a Kidde that was battery only. It got fried due to a power surge and went on to battery only and batteries didn't last more than a few days (twice it went off in the middle of the night to let us know the battery was low beep ................beep................etc. So replaced it with another that is just like the first one, battery only. That one lasted for several years, hoping this one will be the same. Get one whether it is Kidde, or another brannsd. The first one went off loudly and constant in the afternoon one day with a high C02 reading as we had a propane leak to our heater. It saved us. I see that now they have combo fire and C02 detectors and will replace our fire alarms when they need it with those.
