Customer Experiences

"...as I write this,I have that lock sitting on my desk with part of the shipping container door still attached to it!!! It was so hard to open the lock that they cut the container open around it. I'm upset that I was burglarized, but smiling at the same time as I picture these fools beating on this lock till blue in the face only to have to start over with plan B. I would have paid to watch them in the middle of the California desert (115 degree heat) beating on that lock! Thanks for letting me share my story."
