Product review (5 stars): I would have given them 4 stars because they are good and do what they are supposed to do but ...
I have two of these two of another brand and they are all reading the same so I feel they are accurate. I would have given them 4 stars because they are good and do what they are supposed to do but Im giving it 5 stars because I dropped one of them down the stairs while walking down to the basement and it didn't break. I wouldnt try this on purpose!! But I don't as surprised it survived.
A good product for sure.
