Nonsense! The battery is fully charged and worked for the first 3 screws I put into the 1/2" plywood. However, it couldn't complete the process on the 4th screw. The motor kept running like there was no problem, but it just wouldn't turn.I played with the clutch, tried all the settings but it didn't solve the situation at all.Big big mistake, I bought it about a month before I used it because Revain sent it to another site has where I had some work to do so I couldn't return the item, I would definitely not recommend this product.
