“Bought about a month ago, got in the mail in just a few days. Seems to work somewhat accurately. Wouldn't use to determine to drive or not but fun to play with and comes in handy”
“I have been using one of these for over a year one of the best investments I have ever made, like it so much that I bought one for my 3 sons, my twin brother and 2 friends for Christmas gifts.”
“I just received my keychain today. I put the battery it came with into it and tried it out. It seemed to work just fine. But when I went to try it out tonight, it wouldn't even turn on. I changed the battery to a brand new battery and I still cannot get it to turn on. This product does not work at all.”
“I bought one of these last year as a Christmas gift! It was such a hit that I bought two more this year as Christmas gifts! A nice little essential for those in your life who deal with corporate dinner events.”
