My son loves them

Very cool small wheels! I love the colors! I bought these specifically for the rink but eventually I want to explore skate park/ramp skating with them.

I previously owned some Spitfire 101A wheels that were unstoppable on almost any concrete-paved terrain, even is it wasn't that smooth. Bought these to test them, as price was attractive. They don't feel as hard as my previous Spitfire's but they do the work. I usually skate on very harsh concrete, and even these wheels don't roll that much, they aren't the worst. Haven't used them on a smooth surface yet, but i'm pretty positive they will do fine. I feel these are good for an afternoon poping tricks on a single spot, not for cruising around searching for skating spots.
