If you expect it to be a precision tool out of the box, you will be very disappointed. The price of one being accurate upon delivery starts at around $1,800. Before I purchased it I did some research and found a machinist on YouTube who disassembled the same model and showed how to sand the rough edges and adjust it for accuracy. I agreed with him that for the price it was worth a try. When I got it out of the box, all the edges were razor sharp, the slides were loose in some places and bound up in other places. After taking it completely apart, cleaning all parts, using high speed grinder sanding discs on the edges and slide surfaces, realigning the slide bolt, lubricating, and then reassembling, I am very pleased with the product. Because I knew what I would be getting, knew I would have to invest several hours of work into it, and knew how much money I was saving, I would say it’s a very good product. But if you want a polished, accurate one out of the box, skip this one. Take out a second mortgage on your house and buy one elsewhere.
