Quoted from Mundy53:I live in the United States. I have 4 CPR backglasses and 2 of them came to me with what I think is totally unsatisfactory bubbling. CPRs quality control is terrible and their customer service is awful. They know they can get away with it since they are the only game in town.
I know it takes a while to get the glass but I've had nothing but great results over the years with buying from Steve at BGResto. I have bought 9 from him.
