I have red and green, red ones I use for the pusher. But after 3 mts. of practice my Radar tuners were going bald. We practice 3 days a week. Also they are 43 wide so they can get caught up when your skating. Sure grip makes about the same wheel and A friend of mine said hes had his sure grip interseptors off and on his skate for 3 yrs. and the tread is great. He also plays Derby. Atoms are great wheels also. Radars not so much.

These are great wheels! The Reds aren't too sticky, they don't pick up a lot of gum and mess off the floor, and they are F A S T! I love these wheels!

I LOVE THESE WHEELS...I GOT THE HOT PINK QUICK ONES!!

I love these wheels...they are sooo great quality...My friend has the Hot Pink Fast ones...and I have used her skates..and I got the Groovy Green Sticky ones...but Ima get Radar Demons..cuz mine are worn down and I dont have enough money for these ones again...if yooh are looking ferr wheels I would get these...!!!! =P

i mix my wheels with the blacks on the left and pinks on the rights for grip and speed. that set-up works great on all floors (wooden, smooth cement and sport court)!!! the only complaint i have is that i've had these wheels for 4 months and they are balding fast! i'm already looking for more wheels. I'm hard on my wheels with cutting turns, stopping, and jumping. They are great for regular skating but i would spend the extra money for some better wheels if you derby!
