Save your money; it's pants. No instructions on how to set it up, finicky, awkward, unwieldy and frankly not awfully good (but that could be because I haven't set it up right. But hey, no instructions... :roll: ) Plus you need to factor in the two guide clamps, which aren't an awfully good example of the genre either. They tend to slip IME, and the "scale", well what's it for? It slips out of the track as soon as the clamp is anything but horizontal. #-o The Clamp 'n' Guide (now Trend IIRC) and Perform ones I have are much better. If I'd paid full price with it I'd have probably chucked it back at Rutlands, but I couldn't face the hassle.
