I have the original and have been using it on and off for almost 20 years. One bit complaint I have always had is that the peek mechanism is pretty bulky--it makes so little sense to have basically nothing in a small wallet and yet it's still so thick! Yes, it's effective, but it could draw too much attention. Not too mention that it was also somewhat difficult to replace the battery. This new version is SO THIN I just can't even, and the battery is easy to replace too! Throw out the fake gift cards that come with it and put some real ones in there to really sell it. Kind of disappointed that this still isn't offered in leather--the vinyl wallet STILL looks cheap.
