A quick release that makes the name. The build quality is top - it shows already the weight! For the two quick-release buttons takes quite some force to open it, but that's my opinion, a sign of quality. The handling is very good ... Clamping ... draufstellen camera incl. Clamp ... clack sits rock solid ... the safety lever it takes no more Around theoretically ... I do not want to give up the system (Classic Ball 3 II, Q = Base quick coupling, Q = Plate PL1)! Although it costs a little more ... but is worth every euro!
