I guess in any large purchase you'll get a few bad eggs. These bows are handmade and not completely the same from one another but we probably get one return or exchange on every 200 bows. I use my own FM CF bows until the hair is all worn away. Usually for about a year. Instead of rehairing them I just get a new one. So far none have broken and I've tested the strength of the old bows before tossing them. They appear to be super strong. I know that I've had wooden bows break in the same spot.
Ken - I spoke to the maker about that bow.

I wrote to them. LOL
His English is not great but he understands most of what I write.
