You should read some of the movement reviews by The Zigmeisterzumba - pretty enlightening as far as how good an reliable the A7750s can be. With replicas it is and remains a question of pure luck if you get a good one or bad one, no matter if Swiss or Asian...I had it either way
remember als that lots of folks here complain about slipping hands etc., which again I also had with Swiss 7750s, so it is not a perticular problem that the Asia version faces but more of a general problem with replicas
