It's sturdy and moves well. Just sits in a nylon ring, and doesn't attach to anything... But hey... It's $100 bucks. The leather pads are off a bit and will need replacing sooner than later. For the money though... It's a fine first vise for a beginner or a handy person like me that can fashion a better seat for it. But if you had more money to buy the better one... You wouldn't be reading this.... Right?
