Cut an 8 foot by 8 foot block wall. When I was done went to clean it and noticed the blade is not firm, moves sideways a little in relationship to the bar. Tightened the bearing holding nut thinking it might be loose but still has play. Obviously the bearing either had play to begin with or quickly developed play. This explained why I had a hard time staying on a straight line. Needless to say I have to order a $40 bearing plus the tax and shipping right from the start, hopefully this won’t happen every time I cut a doorway. As far as recommending it’s the only game in town
