Ordered from Expert, all the keys copied, a total of approximately 100 issued, tried to open a difficult course castle, crack, run now since about a month around the area, customer service, Locksmiths, no one wants to exchange the unit, or you wait incredibly long on answers, the key itself is actually a good idea, but nothing brings when he says goodbye as soon as a lock is only slightly heavier. Only impressed if the value, then bitterly disappointed, probably never again get the money for the blanks, in my case 9.99 the piece I will. Perhaps we should wait for a stable successor, 2 stars I forgive because I, as mentioned above, the idea find pretty cool and I always advance the mobile phone, or the film have scratched. My biggest problem is that I simply no longer get the keys out and am therefore probably compelled to return it under warranty with the keys.
