I think it Belgicism is nevertheless well suited to the product description. Certainly, it is not expensive, but it is a quality 100% plastic, with all that that implies. Only the screw of the vise is metallic ... All does what it is supposed to do, but I would not recommend it for use on a carrier that is not really stable. In my case, I use it on an exercise bike, home, and although the bike itself is fixed to the ground, the Kindle that this support keeps moving continuously. Also make sure not to over tighten the vice, in plastic as well, and therefore likely to crack if too tight. In short, a little way, then, in my opinion.
