It does everything it says it will do. Good range, loud enough etc. I have one with only one call button, but otherwise it is the same. The problem is that it will spontaneously go into search mode. Then, no matter what I do, I couldn't get it out of search mode. Even taking the batteries for for a few hours didn't help. Finally I left the batteries out for 3 days, then when I put them back in it worked right. The next time it did that, nothing would work, so I left it in search mode and it ran the batteries down in 2 days. Now it is still in search mode, and will not come out. I have to buy something else.
