It looks and feels like a solid product. It works well, but I still have some comments. -The degree setting 0-50° is faded and difficult to see. Not like in the photo. With good eyes you can deduce it. I made 0.30 and 45° visible with a long line with a scratch needle. -You must fix the degree setting with two wrenches, an Allen key 10 and an open-end wrench 19. This is not really useful because while you are tightening it, it can shift. I welded on a stainless steel nut so that this can be done with one hand with an Allen key 10. -The height adjustment is difficult to set exactly. No marking or fine adjustment. I have found that it is easier to rotate the radius saw 90° so that it is straight and you don't have to hold the height with one hand while tightening it. I found the center as best I could and marked it with a scratch needle. -The block with axle is too close to the hinge point. When you clamp a 19mm pipe and want to cut it at a right angle, the hole saw is almost against the pipe. There is practically no space. The manufacturer could solve this by increasing the distance by 1 or 2 cm and inserting a longer axle. Good product, definitely worth the money and easy once I have made these adjustments.
