Okay, let's fix the imperfections. Expensive and not easy. The good points are that the cartridge works properly. I have a very long drill and you will notice any wobble. I see nothing with this drill, quiet with a lot of torque. The extra-long trigger allows for two-finger use, and the change in speed when pressed is predictable, unlike some that go from slow to fast and you can't easily find a middle ground. Some people don't like the key chuck, but you know it won't come off when you use it. If I need to change bits frequently, I can use a bit holder.
