I hesitated to buy this unit for the following reasons: 1) There are very few reviews on Youtube2) It comes from China (neither returns nor warranty repairs would be possible due to the Shipping costs hundreds of dollars) HOWEVER, as with #2, if you can take the risk, this is a good choice. The quality is excellent. It's easy too. It *might* be more fragile than the Zacuto movement. A NOTICE. I'm not using the computerized aspect of this tracking focus, just the manual aspect. I'm dying to try the computerized aspect soon and will update it then.
