The range looks to be a bit like a bigsby, I tried a couple of guyker units and my experience seems to be in the minority. It seems most folks like their stuff and have zero issues. I however have had less than stellar experiences with their stuff.
does anyone have any actual first hand experience with these systems?

No experience with the stud mount one, but I have a top mount one and it works well enough. Feels like a Bigsby but a bit...looser? I imagine due to less string tension since they don't wrap around.
