Been skating if for the past month or so.
Same thickness as jessup, meaning it grips the same and all that.
The grit is for sure more course than standard jessup, however I didn't feel the need to sand it down like a do a new sheet of mob. The grit stays after skating it too, unlike mob almost becoming slick after a couple weeks.
I did however have my first issues with grip tape ripping. Never had the issue with regular jessup but I took a decent sized chunk out of my nose as the ultragrip just kinda ripped off. I've worked at a skateshop for 3.5 years so I know how to grip to avoid this issue. (it was starting to get cold here in montana so that could have caused this particular issue.)
All in all I think its a solid grip option and probably my go to from now on. Just as sticky and easy to grip as og jessup with more grit that last!
