We ordered 20 pieces by replacing what we were using at a series of places such as entrances and exits and warehouses, but they were all different keys and could not be used. I want you to explicitly state that it is a key difference on the net. I understood for the first time in the catalog I sent you.
I used PB padlocks in my neighbor's home center, but sometimes it was difficult to open, and the feeling was not good. As expected, this product is a standard, feeling of use is smooth and I like it. I think that it was ok to price it cheaply from the beginning.
