I have a gvido device, which you seem to be referencing here. If I could return it, I would have, but their return policy is extremely restrictive and basically amounts to no returns. It's waaaayyyy to slow to truly function. It can take several seconds for it to process a page turn, and their official fix for it is to change so that it only turns one page at a time. I make it work when I'm practicing, but I will not use it for a performance, or ensemble work. I recommend staying far away until they can turn out faster devices.
