The vise itself is sturdy, nicely weighted. It feels well made and durable considering it's $300-$700 cheaper than the well known GRS brand. If you can afford the GRS, get it. But if you are a starving artist like me, it is well worth the savings.The attachments aren't perfect but work. The main jaw attachment is designed in such a way that it twists off if not careful. The one side only has one peg so it rotates the jaw piece but it can be worked with.I have set 2 rings with it thus far and I'm pleased. Obviously I don't know what I'm missing not having a GRS but I have found being happy with what you have makes a huge difference in your attitude overall.I would purchase this brand over other generics mostly bc they are more established.
