Everything is fine with the exception of one thing. When you open the lock you have to bring it with in 3-4 ft. from your face. For reasons of the construction and how it fits on certain case. I use them for a 1550 and a 1560. In order for ne to open it I have to put the case at a higher elevation or get on my hand and knees on the floor, simply because of the construction and the way it fits on these particular cases.
Pros: Easy to use
Cons: Careful how you open it
