Now I know they add a file, just turns me off even more ... I'd rather buy a sheet of Delrin and make my own personally if they were my only choice. As you said, just for toys and doubt I'd go to this extent for tuning these lil rc shocks.I have no choice, the only game in town and they do throw in a file in every package...so they must care somewhat. haha
and the product works well and is made of derlin. If someone else takes the time to manufacture these little Derlin shock pistons to perfection for the same price, then i'll order from them instead These are just toys though and these work just fine for now!
