If you are in waters that have a lot of silt and sand, the BOAs do not perform well. They get filled with sediment and can be tough to work. Korkers sent me new ratchets when I contacted them about that. After three years, one of the cables broke. Easy enough to replace but useless until you get a new cable.

Toughest, longest lasting upper I've ever had. Almost 400 days of use and they barely look used (except for the cable).

I've never had a sole come completely out but I have had them have parts that pull out. 99% of the time there's no issue.
