    wow, ok so its here. im in the US and it took about 5 days (but there was a holiday in between). it works great, its so light...the whole thing weighs 68 grams...so your wallet is likely heavier. its really stealthy because it looks like a phone on the top or it can easily be flipped over to look like a little inconspicuous box. the only drawback is the on/off switch seems very delicate.

  3. how helpful with it Review Rating
