The one and only
If you are looking at this then you probably know what this does and that there is nothing else out there that does the same thing. Seems to be quite a poor design (not very sturdy). I think they get away with a pretty crazy price based on being the only product like this and it isn?t reflected in the build quality.
In terms of what it does it is amazing. Check out the many videos online. Reason I bought on Thomann is because of 3 year warranty because I?m a bit worried about how well this thing is built.
