I m not expecting such a good support to the view of some comments totally unjustified. First of all plastic parts are for the design touts the movement are metal or alloy and assembles once I find no game, it is of a very good precision, I feared fixing the dremel on the support it n as n is not nothing, my dremel 4000 fits perfectly into the holder and not moving from tenth after crashes. In conclusion very pleasantly surprised by this support, especially with a price cut to 36 euros. I added today that the carrier has received some modifications compared to the one presented in photos, the quality and precision is diference can be compared to some of the comments?
