[EX Q]: Review: This is a very good concept, but poorly executed. On my particular saw, the tilt section of the table didn't fit flush, so it made the right side of the table useless. Once raised to the 45 degree position, the tilt section was wobbly, as one of the flimsy plastic props did not even touch its rest. The blade ran neither true nor parallel to the fence. The blade retaining nut had to be tightened about every 10 cuts. The blade actually flew off the shaft a couple of times. The tile caught on the plastic end caps of the fence, which stick out. I could easily stall the motor with ordinary 1/4 inch ceramic tile. Can't remember all the other thigs wrong with it, I was in too much of a hurry to return it.
