I did a lot of research and looking around before I settled on this particular vise. I tend to put a lot of credit into the reviews that others write about their experience with products that I am interested in. I start with the star ratings and the number of reviews a product has received before moving on to the written reviews. True... this vise didn't have as many reviews as I typically like to see but I checked it out none the less.When I first opened the package the first thing that I noticed and thought was kind of odd was the fact that they only put packing material on the top side and and did nothing to protect the all so important bottom of the vise. There was no apparent damage but certainly something they should consider going forward. I will give it a closer inspection to ensure there is no damage and for flatness before i secure it to my mill.Like others have said, this thing is a lot bigger than I expected, but since I have a full size mill that won't be a problem. If you have one of the bench top mills the size and weight of this vise could be an issue for you. The next thing I noticed is what I thought was perhaps a milled test block that had been accidentally left in the jaws. After I attached the handle and started cranking the jaws open to remove the block I realized that the block was the jaw when I saw the seam start to open. I clamped the jaws closed again and the seam vanished. The jaw faces are perfectly (as far as the human eye can see) machined.I have not yet attached it to my mill for a test run but I have no doubt that it will provide my desired outcome. Unless something unexpected and catastrophic happens when I put it in operation, and I seriously doubt that will happen, I would absolutely recommend this product.I am certain that one can find a much more precise vise, but for the home shop and at this price I think this is a very good buy.
