First let me say that the only thing I can compare this to is every table saw miter gage that came with all my table saws that I've ever purchased, and there has been many over my 58 yrs. That being said, this is the nicest miter gage I've ever had. This is worth every penny. It's adjustable and tunable to any saw with a 3/4" wide miter slot. The inch markings are pretty much useless, though accurate, I always use the miter gage in the left slot, so the numbers count the wrong way for me, but that's really not an issue for me. I always measure to the blade to my fence or stop, I never rely on the fence markings or those on my miter gage. It's very accurate as far as I can tell. The angle marker is adjustable plus or minus 2 degrees. The key is making sure that your miter slot is perfectly parallel to the blade. Don't blame the miter gage if your slot isn't parrallel to the blade.Did that first! It's very well made and nicely machined piece of equipment. I'm very happy with this miter gage. Worth every penny. Great value.
