Would love to know as well

Very interested also in some Slider Plus clone

I would have gotten the sliderplus clone, but the wing seems to be superior in all aspects, what am i missing?

I have both a sliderplus and a wing. My wing is easier for me to move smoothly than my sliderplus (there's almost always a rough spot or two in sliderplus travel after it's spent some time in a bag), but the wing seems a bit more limited in travel distance.

@eatstoomuchjam: what do you mean by more limited in travel distance?

I see! thanks for clarifying :) and the wing is almost half size of the sliderplus, right?

@fatpig It looks to my eyes like it's about 1/4 the volume of the sliderplus.

I've just bought it over ebay, nicely packaged the pan is a neat little feature, from the little testing done so far, it would benefit from a heavy duty strong tripod to it doesn't kneel over, you will probably find yourself doing a bit of stabilizing in post, I really like the idea of it, as with all types or most types of sliders specially at the low end of the cost scale it won't be the most amazing thing, probably need to experiment much more to nail down the best setup for it.

Wow the Viltrox version looks so bad for smoothness near the ends in the "panning" mode (gt-v70). The normal mode could work I guess but without some sort of flywheel is at the mercy of shaky hands.
