I really hate to be very critical of "good value" products for skates- I've been buying "good value" wheels for over 10 years. However, my purchase of these wheels leaves me wondering if they didn't come from a bad batch. After roughly 15 miles of street skating, the wheels are much more coned than I would have imagined and there is nothing fast about these wheels. I feel as if they are 72a- not 82a.
