I've had my little flex 940 for 4 years now and it's been very good to me despite the low cost. I've strung around 300-400 rackets so far. The only issue I've had is the threaded rod stripping out of the swivel clamp handle. Eagnas want's $24 for the little cast handle which I bought a few months ago. Now the other handle is stripped and I'm thinking about replacing the whole handle/bearing assembly with quality parts from mcmaster. Anyone else having this issue?
