    Great price great product.

    Got early great shipping. Followed directions to a tee. Worked perfect. Cut through tile with very low effort. I highly recommend. Cut a 30 mm hole in seconds through tile.

    Great deal

    Great deal for the money. For very high use, you may want something else, but the range and price are great for occasional use.
