Top product, good finish, BUT ... It runs great, even on roads with gravel (there is a little puzzle g ...) The weight is there but not too bothersome. Compared to a ski skating, it's a little less stable (this is normal wheels ...) suddenly we quickly feel a difference in stability between the leg that has the brake, right, and one that n 'none, especially if used as rollers. The brake has a double advantage: He brakes when necessary (normal ...) but especially as it offers a high supports it provides a much better lateral stability. I have mine with a brake on the left leg and it is disproportionate compared to before. Finally it slows well in the dry, in the wet with dirty wheels must lengthen the distance ... No pb for inflation with a small high-pressure pump pump type of ATV dampers.
