Thanks for the review. I’ve been skeptical about this piece of gear but you made some good points so I’m getting it to test it on some wedding videos.

Where do I start? What a nightmare of a god awful product. If you want to flush about $300 down the toilet, do that instead of buying this piece of trash. Think about it. If you flush the money down the toilet, you can film it with your phone (which will actually focus) and you'll have that video for life. If you spend the money on this garbage, you'll have a paper weight with some decent packaging. I followed these steps in the video with my device and everything was fine except upon completion, it doesn't work. The video says to recalibrate it again if there is an issue. So I did, following the steps exactly as listed in this video. Nothing. When I can get something in focus, the motor does make a feeble attempt to keep it in focus I guess, but it fails pathetically. It doesn't matter if I move fast or slow, or if the subject moves fast or slow. It can't keep the focus assist card in focus which is stationary, taped on the wall, even if I step back at a snails pace. I mean what's the point? Just a useless piece of equipment. If you're looking to spend almost $300 to get pissed off and smash your head into a wall, consider this. Pay me $150 and I'll come smash your head into a wall for you and you can save about $150. Long story short is you get what you pay for. In this case, I paid $300 for a trash product. Don't make the same mistake as me.

Thanks you so much review, came from the pdmovie comments, cheers
