I can't rate wear and tear yet. Therefore, so far only honest 4 stars for the fact that after viewing the ratings and tests, the choice was justified. Got pros: Really quiet. Which is what was required. The sound is not annoying at all. The traction is good. The build quality seems to be good. Wire connections are closed. The cover is removed easily. Has some cons: Minor drawback - the cable connection could be made more modern. Not the stone age in the yard. It will, but still.
