Document: I took my time shopping around for a bench vise, and finally decided to buy this one. I'm glad I waited. This is pretty much the best bench vise you can buy in this price range. In fact, I've seen others priced 2-3 times as much which weren't as nice. It's rock solid, and super functional. It swivels and rotates too. The only drawback is you can't rotate the head once the vise is tightened. It must be in the open position in order to move.
very useful vise - the rotation feature is quite handy however it is a bit bothersome to have to clamp the vise in order to keep it from rotating. I did make a permanent 0 degree mark to help in alignment. I bought this to replace my old Craftsman and am more than happy with size, durability and ease of use
this is a heavy muti use vise that is perfect for every job. well built with every use in mind
love this vice heavy duty beautiful this is the best vice out there for the money i recommend this vice
i gave it only a 4 rating because  i felt the two screw down are not as strong as my other one, over all not bad for the price
great multi-purpose vise. super buy fast ship from grizzly tools and well made. fantastic buy.
Very nice vise. The only shortcoming is that you can't lock it upright without locking the jaws. I wish Grizzly would send an information sheet with the vise. Otherwise, I'm very pleased with it.
Very high quality vise. What can I say.. The vice does not lock in place while open, so it can be a bit cumbersome to use when trying to get your workpiece in the right position but once it's locked down no further issues. I think the only thing that would make this vise better is being able to lock it in place while the jaws are open.The thing is very heavy too.
This vise is very heavy, well made, and looks amazing. All sliding parts work perfectly with no slop and great clamping power. I have experienced no problems with it in any way. There have been some negative reviews about the jaws rotating freely without the option to lock in a fixed position, but this is not true. The jaws can be locked in place so it will not rotate by tightening a couple of screws on the back side of the vise. I love this vise and highly recommend it.
This is an extremly well manufactureed vise (heavy). I have used it for my mechanically needs as well as pipe work. Great tool for the money. And yes, have a rag available when unpacking.
