Title: Did not do as advertised
Review: Bought for a Black & Decker jigsaw to cut circles. It fit okay in the slots provided on the saw, only the leading edge of the edge guide was about 4.5" behind the the blade, so it could not work. It will, however fit a Skil circular saw and a Ryobi 18v circular saw alright, meaning not very spectacularly. It's better to find scrap wood or get a small piece of hardiboard to make a jig for circles, and clamp a long straight-edge to the board if you need a guide. Pass on this one and make your own for cheaper and less headache. At the very least, locate the guide slots on your tools before purchasing.
