I have 2 Metabones adaptors. The EF to E mount SmartAdaptor that I use on the Sony NEX-FS100 and the Nikon to MFT SpeedBooster. They are manufactured to a very high standard. I'd say probably a higher standard than most lenses from the big manufactures.
These standards in smaller runs cost money. They don't have huge volumes to bring the costs down.
They also have R&D costs. For example: The aperture control of Nikon G lenses in the SpeedBooster is the best I have yet to use. A lot of though has gone it to that. The Caldwell lens design is very very good. It's almost totally invisible even when used on very expensive Zeiss glass.
The LensTurbo is just a copy. And their first version was so bad they had to offer a replacement to those early buyers. A few of whom are on this forum.
I can see the appeal of the cost saving and if I was just a hobbiest I'd probably consider the LensTurbo but as I use my kit to do work for paying clients who expect professional results. So I tend to invest in kit I can rely on and I'll pay a premium for that.
