Pros : I used my mom's ring saw for years, but happily decided on this when I went to buy for myself. There are some great advantages including the significantly cheaper blades, clear up and down direction of the cut and ease of use. When I first got it, I had to put it together, a little tricky, but the instructional video that comes with it really helps. The large work surface is great. Though it's large, it's not too heavy, and I can move it between workspaces. It makes very clean intricate cuts, though like the ring saw there's a learning curve to make your cuts smooth.
The water supply is very consistent and every stays wet and cool.
Cons : The steady water source can obscure your cutting lines. It's fairly noisy and can create glass shards, but I found the same thing with the ring saw. Until you learn the knack, it's a little tricky to take the work surface off for cleaning.
Other Thoughts : I found that water builds up on the work surface and along the glass very quickly. If you're working on anything more than a couple of inches, water will spill off the sides. This machine is very tall and not portable. It's best to just set if up and not have to return it to the box very often.
