Exceeds Expectations
I haven't used it a lot yet but the time I have I was very surprised lots of power, it ranks right up there with its corded counter part.

Good grinder for its size and battery powered
I put it to test cutting large it got a bit hot from load but kept cutting. Cutting tile would be easy after that.

I would most definitely buy this product again.
I primarily use the 7" / 9" grinder for material preparation and light finish work at my job as a fabricator. However, on the weekends I used it to prepare tires on my friend's dirt race car. Corded power and very reliable.

The tool overheats very fast and will overheat a 12AMP battery in minutes. I can cut more with the smaller grinder and not overheat the tool.

I`m a plumber,and it`s a plumber`s tool. BIG!
Every job is full of things that need to be ground down, cut , shaped to fit.Being "cordless" alows you to get in to "tight" places. Sometimes your working in wet spots with less danger of "electrocution". There`s not always "power " on the job. Good balance, strong long lasting battery.

Use this grinder a lot, it’s very versatile because of no extension cords and able to switch between the 7” and 9” grinding and cutoff wheels. Best part I don’t have to string out 300 feet of extension cords.
