[Q]: We give this product high marks for ease of set-up and are satisfied thus far with the speed of the processor, which was an area of slight concern when we purchased. Recommended for word processing, Internet browsing, etc
[A]: positive

[Q]: First of all, they took a long time to get to me. They come with no instructions. No way of knowing when they are fully charged. Charge doesn't last long, at all. And they scratch very easily. Very disappointed with this product unfortunately.
[A]: negative

[Q]: This product never worked right from the beginning. One of the sensors doesn't work. The other sensor has been through four sets of batteries in a month. The manufacturer does not include information to contact them about this crappy alarm. Keep shopping, and don't buy this one.
[A]:
negative
