If you are talking about Noob, H maker, Zfac, KW-V6Fac ... and other good makers of PAM reps the quality of the working of the CG lever is really good. Precise and thight.
Obviously we are talking about reps which cost 20-50 times less than a gen and the uniformity is not at all as in gens.
Usually the lever has good tightening and is not loose at all, but you could have some variations regarding the snap more or less strong. But always correct and acceptable.
That will not be the main problem of a PAM rep
