I bought one of these for my wife for Christmas, and after only about a month of use, the battery fails to hold a charge even long enough to do a 12-point measurement. Every attempt to contact the company via email, website, Facebook page, etc has been ignored. Please save yourself some frustration, and find someone else to give your hard earned cash to. The device is a great idea, but the the build quality is horrible, and they don't stand behind their products at all.
Bottom Line: No, I would not recommend this to a friend
