I’ve used for a while now. It does what I want it to. It is not as well made as GRS by far, but it is a fraction of the price as well.The pins are all loose in the holes. At first, I thought I wouldn’t be able to use this way. However, when placing the pins correctly around the piece you’re doing, and adjusting the vises tightness to the piece you’re working on, it works and holds the piece just fine.I also cut some small dowels to use if needed, that are the hole size, but have not needed to use them.I did about 80 flush sets and did not have any problems at all with this vise.I especially like how it rotates in every direction to allow better ergonomics on my hands, wrist, neck, etc.
