The new ekey for iphone

I do not know how many of you out there have tried the new ekey for iphone.  It is awesome.  You do not have to worry about losing it or even charging it.  The main piece stays on your key chain, and when you are ready to use it you just take the cover off, and pop it into where you usually charge.  It keeps an inventory, and it keeps track of all your lock boxes.  Personally I think it is awesome, but I am one that loves all technology.
