Purchased the year before. At the moment, thirteen thousand people were skating on them. Even though I haven't ridden them in 13,000 miles, all of the wheels are still intact, there are no bumps, and the wear is scarcely evident by eye. Yesterday I went to the garage to make ready for changing shoes, and despite the fact that I haven't ridden them in 13,000 miles, all of the wheels are still intact. In terms of its driving characteristics, the behavior of the rubber is predictable on the primer; it does not deviate from the intended path; it travels confidently on dry and wet asphalt; and it does not cause interruptions when it first gets going. While it is audible on the highway, particularly when traveling at high speeds, the level of noise is noticeably reduced once the vehicle has been rolled. Her comfort zone is light off-road (she didn't climb into the mud), but she has no issues with the dirt, stones, sand, or grass. There are no complaints. In general, the rubber is of high quality, and I have no complaints about it.
