Never used this brand so didn't know what to expect. First impressions, this clip is pretty well done. The workmanship is good and I can't find any flaws in the design. He is healthy and strong. It works exactly as it's supposed to. You say it's possible to work with one hand, but I don't see how that's possible since you have to press the clamp firmly against the workpiece and then snap it in with your other hand. Although I think you could do it with one hand once you get used to the clamp. I use screw terminals so they're probably just different for me. The clip fits my Powertek rails perfectly, slides right in and holds well. So it should also work well on Makita and Festool rails. The only criticism is that there is no "topping" on the part that presses against the workpiece. Just see how it leaves an imprint when pressed firmly. It would be better if there was a rubber seal to keep the clamp from messing up your work. It seems a bit long ago that most people use chainsaws to break up sheet material. Again, it's best to have it longer when you need it. The price seems a little high but it's quality so do you get what you pay for? All in all a good clip and I would recommend it. I like it.
