I bought a pair to go with my all in one trainer. They're great cups however the fit was a little loose causing the cups to tilt forward. This would make the bar roll to the end of the cups. To fix this I stuck on some black velcro to the bracket. The added thickness now makes for a tight fit and the cups now sit on the upright properly

Perfect Simple J-Cups

They're big and sturdy, the bar slides great on the protective shields which are on all three contact points and the BOS on them is a nice little touch. Read full review

Bought my second pair of J Cups from BOS (my first being the roller cups) and I couldn’t be happier. The reason I bought them was it’s easier to have an additional pair instead of constantly having to remember where you placed it for squats or bench and I found these to be more stable for benching. Shipping was fast and material is solid overall

The laser embedded logo is killer but would be a show stopper if the background came in different colors instead of black on black. Definitely will buy more from them in the future.
