80%, great for the price, but...
The advertised "Precision ABEC bearings", is misleading, the ABEC is a rating system of 1, 3, 5, 7, & 9, the higher the number, the smoother and easier the ride, you use less energy to propel and maintain movement, simply being "ABEC" does not mean it is high quality, the wheels come with ABEC 3, that equal to a quality rating of 2/5 and they are cheap versions at that, replace them with no less than ABEC 7 or ABEC 9, The wheels have a low rating on the hardness level, probably in the 70's, the durometer or hardness rating does NOT suggest quality, the lower number/softer the wheel the better the grip and they are also fairly wide, better for beginers and/or outdoor skating, if you are an experienced skater and are going to be doing rink skating only , I recomend the 90's or higher and a slimmer wheel, around 54mm to 62mm height, but 32mm width, experienced skaters will have far better control, a quality set of 8 "54mm*32mm" or "62mm*32mm" wheels are pretty inexpensive, but a quality set of 8 or 16 ABEC 7 to 9 bearings can cost in the $30's-$40's +/-, other than that, the skates are great for the begining skater or the once in a while experienced skater and much safer than the rental skates at rinks, other than the suggestions about the bearings and wheels, the Chicago deluxe edition seems to be a good skate at a great value, (just for reassurance, the Chicago Skates company has been in business since 1905 and are famous for the for their moderate to high quality products.) have fun :)
