I was very impressed with the customer service. They sent this part out for free after I sent in a email about the lock keys not staying depressed once opened. Calvin emailed and explained this is an issue they are working to completely take care of b it does not compromise the box, the keys just have to depressed to close. In the meantime parts are doing great right now. Honestly I think we shut the box without anything in it and that compromised the part. I just replaced tonight and it was super simply. I really like the features and utility of the stopbox.
