After much consideration I decided on this Capri Vise. Build quality seems very good, jaws line up perfectly. You can adjust the tolerances for the main slide - the set screws shown. I took it apart and gave everything a good grease. The advertised weight is right on (I checked) at 21 lbs. Not the biggest vise but opens nice and wide and is fairly deep. If you look around at the competitors you will find one that is exactly the same but the Capri brand was $20 cheaper. Of course time will tell but I am happy with my purchase.
Just installed it on my work bench and seems of good quality and performs as should. Probably over kill for my needs but you never know and i wanted some quality
