After about a month or so, I have had no major problems with this saw. I love the blade changes and tensioner. It did have some vibration at full speed. I have it mounted on a sturdy 2x4 and plywood stand that I built. I did purchase some good blades, the ones that come with the saw are cheap and do not do a very good job. I bought Flying Dutchman blades from Mikes Workshop and they are great. It is a very heavy saw, not something you would want to move around a lot. I would also recommend purchasing a work light for it. If not for the slight vibration and cheap blades, I would have rated it five stars.
