Q: The first tile I cut... I knew I had purchased the wrong saw. Maybe to use the rip fence it would work ok, but to cut tile freehand, it was useless. The blade comes up through the table, like a table saw, with the blade spinning through 1 inch of water in the bottom of the tank. The blade picks up the water and sprays it all over the inside of the clear guard over the blade. This makes it impossible to see any lines marked on the tile. It is impossible to make an accurate cut if you can't see your cut lines. Using the saw without the guard is not an option, unless you are working outside, and don't mind getting drenched. Bad design. I'm returning it and spending the extra money to get something good.
A:
Negative
