We've never had VukGripz before, but a teammate had one and I could see the science behind it being effective. I went with this black with blue and white as an alternative to the color I really wanted, which was black and baby blue. Those are my son's team colors, but that colorway has been sold out for several months now. I put the grip on a custom wood bat I got my son for Christmas, so he hasn't swung it yet to test it out. I'll try to remember to update the review after Christmas. The bat has what's called a comfort knob (basically it's just a taper with no actual knob at the end). I was able to wrap the bat all the way to the end of the knob (and slightly around the end) with no wrinkles or issues following one of RJ's VukGripz tutorial videos. It went on really easily. I would suggest though that if you're gonna wrap the knob like this that you get the XL tape. This regular one ended up pretty short. My son is young and has small hands so it won't be a problem, but a grown man with big hands would end up having the top finger or two above the grip.
All in all, it seems great so far, and I'll likely buy another, especially if the black and baby blue ever come back in stock...XL in that colorway would be even better!
