So far so good. Generally well made except for 1. the Ni-MH battery holder - thin and fragile and 2. the wheel when tightened is loose and rattley 3. the battery chamber latch seems fragile. The main body has a good feel and appearance and except for the inferior latch quality it would be difficult to distinguish it from the real thing. I can't understand why for a few quid more that the manufacturers don't boost the quality of these bits. If they did it'd be as good as Nikon's any day. It's worth the money for me for something I shall use infrequently ie for very rapid bursts of fps but wouldn't want it if I depended on it as a pro.
