The knurled grooves on these cups seat the bar so snugly that I barely feel any shifting on heavy squats, which is exactly what I wanted. Setting the bar down after each rep feels rock-solid, and the upgraded design makes racking and unracking noticeably smoother than my old set.

The thick UHMW lining grips the barbell so well that I don’t even bother re-racking my squats anymore—it just stays put. Installation was a breeze and they feel rock solid on the uprights.

Had a bit of trouble adjusting them at first, but once I got the angle right they grip the bar perfectly and my wrists feel way less strained during heavy presses. The wider contact surface really does make a difference compared to my old hooks.
