Title: Works for me and reasonably priced.
Review: I purchased this wireless water alarm because I could not hear my "basement watchdog" alarm over the sound of the water recently when I was taking a shower. 30 more seconds of shower and my basement would have been flooded. Good thing I quit the shower when I did. All I ended up with was a laundry room with about 10 square feet of concrete floor covered with water and no damage. So I did a lot of research and in spite of a few negative reviews which I read, I purchased the Sonin. It works excellent for me, but I only use it over a distance of about 15 feet from the basement to the upstairs bathroom. I am buying another one for our second bathroom. As far as the fact that some people don't seem to like it, maybe they are placing the receiver a bit farther away from the sensing unit. I am very pleased with this product.
