The concrete saw I bought is great. The only concern is that I couldn’t tell the difference in the 300 and 300+, on Amazon. I thought the 300+ came with a blade. So, I bought the 300 and a blade for it. I also bought the wet saw attachment on the Evolution site. When I received it, it did have a blade. So Onhave two, which is okay. But the 300 doesn’t have the hookups for the water attachment. So have this $70 tank now that can’t be attached. And the saw I have is a dry saw, when I intended to buy the wet saw. My feedback is to make it more clear that the 300+, is a +, due to the water hookups, not the blade.
