For the price really great. The rollers run "ok" on hard / smooth surfaces, but really excellent when things get rough. Then the large diameter is better over bumps than minor roles. Grip is also great for Sliden I have not yet but brought. But my opinion is not really the domain of such monster roles. You can feel naturally at pushing the inertia during acceleration, but when they are run once it class. Definitely pay plan that the board provides enough space, Wheelbite is damn uncomfortable.
