Didn't come with the blade change wrench
Reviewed in the United States on April 9, 2019
Seems to bog down more than the cheapest Ryobi plug in you can get, but WAY more convenient. Run time is long, but again, you may spend that time waiting for it to get to speed again or tasks taking longer as the tool is running slower - I see this being the biggest problem when grinding masonry. I guess I'd say if you're grinding things you probably wanted a corded model.
I bought the "tool only", cheapest I could find on Amazon item and I'm not sure if it was or wasn't supposed to be this way, but the wrench you use to change out blades was not included. What was included however was a giant allen wrench that does not appear to be related to this tool. Not sure whats going there but I'll have to share blade change tools between my grinders since I didn't get one with this.
