One failed right away

How do you know if these devices will work if one doesn't work out of the box and the other 2 don't seem to test themselves as faulty are they good? I wrote to the manufacturer, received NOTHING. Return these items as defective.

Pros
  • Sturdy construction
Cons
  • Dull packaging

One is not working properly

Everything seems to be working fine except one of the carbon monoxide alarms keeps going on. I've tried installing and removing the battery several times, it keeps exploding. I think a block is broken. I only have 2 others working for me.

3 packs at a great price. Easy to install and test. batteries included.

This 3 pack appears to be very good value for money. They are easy to install (with a drill) and test. The indicator flashes every 15 seconds to let you know they are on and working. I think it's great that there is one for each level of our house. Each of them runs on two AA batteries, which are included. Happy to have it.

  • New

Manual not easy to understand

Instructions not in good clear English. Looks like they used a computer translator. I would really like it in clear English. It's really not that easy to understand. One of them turned out to be defective, it worked, and the fire department told me that it was defective. The other two are okay. I had them very briefly.

Pros
  • Good product for the price
Cons
  • Some difficulties

Great value great quality - now you can sleep at night

I've only had them for about a month and luckily there weren't any leaks in my house so they haven't been fully tested. The earlier the detection, the better. The detectors are of good quality and worth every penny spent, amazing value for all three. They were really easy to install and now that I have them I feel a lot more confident.

Pros
  • Pretty impressive
Cons
  • Little things

Don't trust them with your life. Absolute rubbish.

Bought three packs and installed them in my pantry while waiting to brew beer in a semi-enclosed area (I have a garage-sized door and a massive storage fan for ventilation). I never bothered to brew beer when I installed these three sensors on my ceiling and let them run for about a month. After 3 weeks everything started to chirp. Okay, I replaced the batteries. After replacing the batteries with new AA batteries, one of them started warning that there was 175ppm in the area. The other two…
