Review on 🛼 STMAX Quad Roller Skates for Girls and Women - Size 2.5 Kids to 8.5 Women - Perfect for Outdoor, Indoor, and Rink Skating - Classic High Cuff Design with Adjustable Lace System by Calvin Hodges

Should have listened to the reviews! The skates look good, but the wheels don't turn; no revolution. I loosened the nut and it made a maximum of 1-2 turns. It turned out that the wheel bearings and race are of poor quality. I work in the automotive industry and have about a dozen types of lubricants and car oils. I ended up using full synthetic gear oil to lubricate the bearings because the thicker greases didn't make the wheel spin better. Also, the nut used to tighten the wheel makes contact with the outer race of the bearing and this is just an unfortunate design by the manufacturer. This problem can be solved by purchasing a washer the size of the inner ring. Much luck
