Bests & Worsts Reviews from Amazon

i purchased this after seeing all the great reviews, and thought this would be a great addition to my toolbox. first time i used it, i ended up with a 10" cut on my leg as the guide prevented the safety cover from snapping back over the saw. so, and ER visit and 17 stitches later, i thought it was totally my fault for not paying attention (and i take part blame for not checking on the safety cover), i thought it was the saw. so i tried another...the first was craftsman, and second was ryobi. appraently the ryobi didn't fit either. so for a "universal" guide, there's two fairly popular brands it didn't fit. i'm contemplating sending it back as i most likely won't be using it again...i just don't think the ER and i should be such good friends.
