ELRO FS4610 (10 years) 4-Pack

The copies I receive are beeping at random times. Sometimes they are quiet for weeks, but then you are suddenly unpleasantly awakened at night by a short beep. Repair by Coolblue did not remedy this shortcoming.

Due to the low profile design and good reviews I bought three of these smoke alarms but I don't trust them. Unfortunately, the beeping only started after 30 days, so sending a free return is no longer an option and according to the helpdesk I can only get my money back after the smoke detectors have been repaired three times. This is not the service I expected.

looks much better than other smoke detectors, but does have quite a few flaws (see negatives)

Very fine detector, nice modern design and very thin. I also really like that the battery lasts 10 years. This way we are fully equipped for the next 10 years. I read from a number of people that they are concerned about the fact that the battery is not removable. However, a smoke detector sensor usually only lasts 10 years ;-D So it wouldn't make sense ;)
