Weak hinge
I recently ordered this device, decided to go with this device due to the fact that it had a rechargable battery.  Definitely a bonus considering how often you may have to replace batteries in other similar devices with frequent use. Upon receiving the device, in the mail, I was very eager to get it fully charged to see just how well it actually worked. Once I had it charged up I tried it out on myself and the reading came back very quickly which I was very pleased with. It's not too hard to figure out how to operate to switch between modes and views which again very pleased with that. On the downside though, the hinge for your finger placement seems very weak maybe it just so happened to be mine based on the fact that no one else seems to have mentioned that in their reviews but I'm afraid that with frequent use this hinge may eventually snap all together. I don't really want to return this item due to the fact that it is rechargable so I'm going to see if there is a way to maybe tighten the hinge so it doesn't seem as weak, but if it doesn't appear like there is any way to reenforce the hinge I very well may be sending it back. Therefore the weak hinge is the reason I'm rating this at 3 stars.
Rating: 3 stars
