Got this after struggle with a smaller vise. These are modelled after the famous design of the American Kurt vise, but at a tiny fraction of the price. So wasn't expecting it to be as good as it turned out to be. Was well packed, came with a fixing kit, and was no trouble to setup. After fly cutting a part both sides on parallels the thickness was almost same on all corners (just over 0.01mm). Extremely good clamping force.
