I had the same model and I was very satisfied. However, the new one is not the same as the old one. Now they use the box with the plastic lid instead of the metal one as shown in the photo. Also, something else that I didn't like very much is that after a short period of use, it shows a slight instability in the rotations. Time will tell if it is as good as the old one I had. However, if someone has to choose between this one and the model without brushes, the new brushless technology is much better.

I bought it without batteries (because I have a Dewalt drill), very powerful (I have 4ah batteries), practical tool, even if the battery level drops, it will continue to work, albeit at reduced speed!! With heavy use, the battery level (4ah) will decrease. The locking mechanism in the middle of the switch is very good for safety.
