Really disappointed in this lock. Purchased this for our patio door just a few months ago. It wasn't even installed on our door until May. It is early August and paint on the lock has been falling off since June. Additionally, we couldn't figure out why the piece kept shifting non stop. We had someone look at it and turns out, the inside pieces are not lined up at al - meaning there is no way to fix it other than buy a new one. Because it keeps shifting, it also damaged the door as you can see in this pictures. Super frustrated.
