In short I love this tool and I'm glad I bought it. Now the story, I spend a lot of time off road in my jeep and drive through a lot of unlocked gates and always worry about being blocked by an accident blocking my way back, trail repairs can also be an issue so have I started looking for a battery-powered cut-off saw. My package from Revain arrived a day earlier than expected and due to all the pandemic concerns I put on rubber gloves and packed my box in the garage for unpacking and now a routine sanitization of all items delivered. The sharpener was well packaged and my first impression was that it is a quality tool that is unmatched at the local big shop, the battery is also a good size and fits the tool well. Picking up the charger I was pleasantly surprised that the battery was fully charged for the first time for me as it is never full when it arrives. The instructions are usually poorly written and simple and clear to a person with little knowledge of English, and provide excellent information on how to get the most out of the grinder. Another plus is the range of grinding wheels and even the 30 tooth carbide blade, all of good quality. A good tool, a set of wheels, a charger, all in a sturdy zipped carry case, not the most important, does it cut itself? Yes, the soft start motor spins the blade with ease, picks up speed slowly to high revs, hits the lock, there was no sense of power loss, and the blade cut into the lock with ease. I made a few more cuts after the first one was removed with no loss of power. It's a great quality tool that you will be satisfied with and with minimal maintenance it will provide great service.
