I came in hesitant after using a friends Wilton 6" vise, I realized I needed an upgrade over my ancient 4" vise. Not wanting to pay the price for a high-end Wilton I found this. Feature wise, it matches up to it's higher-end and pricier competitor. Outside finish is good, jaw and hammering surfaces were milled smooth and level.
My main gripe, and it only exists because I came directly from using the Wilton, is fit quality. This vise has a log of slop/play in it. From the threading (opening/closing), and from the outside jaw being able to swivel from the fixed jaw. This is the major issue I have. As it makes closing and having the jaws actually align a major issue - if that's something you need from a vise. It's able to swivel about 3-4 degrees, which doesn't seem like much, but it's enough to make it so that either corner would sit 2-3mm (1/8") off from flush.
The other quality issue is in the casting, or lack of clean-up on the casting. I took it apart when I first got it to grease the main thread, and found a lot of casting/milling swarf on all the internals. Basically this thing comes out of the casting, is milled, and then painted with zero final cleanup performed. Some burs were enough to slice a finger open easily. This can be slightly overlooked since it's all internal, and all outside features are fairly smooth, but just goes to show it's not a high-end piece.
But even with those gripes, it's still a strong vise, with the features I needed at probably the lowest price I could find, so simply ensure you set your expectations and you'll be fine.
