I lived around the corner from B&V so these were the logical guys for me. I was a customer for years but kept wondering why my shirt buttons kept cracking. I showed them to my salesman at Brooks Brothers and he said "change dry cleaners". He said that Brooks Bros. used really tough buttons and the fact that these guys can break them means that it's time for a change. Change I did and I have not lost a button since.
People use them so they may be OK for you but I do not any more. They were too careless (in my opinion) and I no longer trust my shirts to them.
