These wheels are awesome! I was honestly a bit skeptical at first for the fact that most wheels these days that are light up or along those lines, aren't exactly made for rough skating. These glows have changed that, with the very bright reflective outline, they are highly visible at night, and they are really grippy at high speeds, yet surprisingly will break loose easily for a nice slide when needed. All In all these wheels are great for night or day shreds. Thanks lazyrolling!
