My wife is physically disabled and needs help getting up and getting up from the sofa, bed etc. She often takes naps during the day and I go out and work in the garden. I was looking for something she could use to warn me that she needed my help. We have a baby monitor which is good at night but not so good during the day because I can't hear her call on my portable speaker when I'm outside. I ordered another call system from Revain but the range was very short (20-30ft). It's the one with the red panic button. Upon closer inspection I found that they are all identical and are probably all made by the same manufacturer in China and sold under different brand names. A socket is also required to connect the alarm. It has long range, more than 60 feet in my house and multiple rooms. The big advantage is that the alarm clock is battery operated, which makes it much more portable and you are not tied to an outlet when you are outside. The only thing that could be improved here is a belt clip to carry the alarm clock and maybe a vibrate function. In that sense I am very happy with this purchase. If anything goes wrong, I will adjust this review accordingly.
