Top critical review
16 October 2017
Every reviewer except 2 (@ the time of writing) has been happy wifh the alarm volume. I was not. I expected something at the loudness of, for example, a smoke detector - which is required to be 85db@3m. This device claims 140db AT SOURCE which means, I suppose, that it's pretty loud if you hold it to your ear! In a noisy urban environment I would not expect it to be that noticeable. If I have a faulty device, then let the seller contact me in the comments. At the price, I can't be bothered to return it and I might think of a use for it.
