GX1000 board was the worst board i've ever had. I skated it an hour and a half, went home, and set up an old board. It's been in my closet for over a year and it pisses me off everytime I see it.
Ricta wheels. I fucking despise Ricta wheels. Never had a wheel so slippery and prone to flat spots. The sound they make also sucks. Walmart-ass wheels.
Vans shoes. Every pair of Vans shoes i've bought after 2012 was terrible. Side panels tearing, soles coming apart just walking, weird creases, inconsistent sizing/fit and more. I will never buy another pair of Vans, I don't care if they've gotten better.
Reflex bearings. Doubt they still exist, but I destroyed 4 bearings in one session. Always keep spare bearings in your car, boys and girls. Had a similar experience with Speed Demons and Lucky.
The only Krooked board I've ever had (2012 Mike Anderson) chipped horribly. It felt real dry and was a complete mess after about 10 days..
