I’ve had two other jade rollers that both cost about $15 for just the roller - and they were both garbage compared to this one. The jade rolled unevenly, the metal parts kept falling apart. I was fine with it because well, they’re cheap. I lost my last one and went to order a new roller, and this one was a set for the same price of just a roller, so I gave it a shot. Huge difference in quality! This set is amazing, the roller well crafted, the quartz smooth and rolls well without any scraping noise. Highly recommend.
