The vise did not have any bolts that fit through it, so had to upsize the holes to fit the bolts that came with the blocks. The piece that goes into the T-slot is cheap, thin, and very loose tolerance, I would suggest just making T blocks for it. It is metric approximated to imperial so all measurements are to be taken with a grain of salt. The inside of the vise fully extended does not reach 2 inches or 50mm, or anywhere close to it as its short by almost 1/4 inch. The vise itself seems well made as in rigid and made correctly, but to metric standards. If your job is a machinist then nothing on it is unfixable, but if you need something that works right out of the box then buy something else. Overall would not recommend buying anything from this place again.
