Nice addition to your tool collection. I needed a Briggs & Stratton engine mod grinder on a John Deere lawn tractor to replace the factory spark plugs. The Dewalt Die Grinder worked well as it's compact and easy to make changes to the aluminum with the bits I also bought. Dewalt looks good and was easy to set up before first use. Remember that you need to put a few drops in the opening of the air injection hose and first wipe it with a cloth or paper towel, covering the outlets in the same area. They also recommend putting a drop or two in the opening of the air hose before removing it. Also, the 1/4 inch thread that attaches the air hose fitting is under the inverted rubber cap. I made the mistake of removing this part first, but it was easy enough to attach and reattach some teflon tape. I've had good success with other Dewalt products and it looks like this one will be available for a long time. It's made in China, so we'll see if that affects durability.
