Product review (5 stars): No Sweat
It's probably not providing accuracy to review something like this right after getting it, and not having extended time to see it's performance. So far, the item seems to work nicely, is easy to read, and has a nice magnet on the back if you want to stick it to something metal. It is used for an indoor pool and hot tub area. We had back luck with another brand, with 4 of them each dying before being a year old. Hopefully this one will last longer.
