After 1 month of shredding:
First oak wheels I try and they feel amazing. The "mucho feeling" is more than just a motto,it's the truth! By the way sometime too much grip makes some tricks really really hard (but this is the price to pay for the great feeling),this is why four and not five stars. The wheels are actually very big and this is really comfortable on vert obstacles,but it gives a little extra-weight too, to the setup, that makes flips rotation more clean and so more stylish!
If you want to pull the best out of these wheels ,I recommend using them on marble surfaces and not on wood---> The too much grip is perfect for really really smooth surfaces like marble or glass but can be a limit on wood and concrete. This is just my experience and opinion and the feeling with these wheels can be different from person to person. Enjoy!
These are my first ever bearing wheels and they feel amazing. They provide a smooth ride and roll perfectly.
8 mm long and 5 mm wide makes them look stunning. After a very long time, they'll start to get a slightly different colour like real skateboard wheels.
Worth your money.
