The Hart 20 volt cordless impact driver is a great drill! It has a nice weight to it. I felt like I was holding a powerful tool; but it wasn't so heavy as to cause fatigue. It is comfortable in my hand. I really love the grip. It is soft but doesn't slip. This drill has some serious torque so the grip was especially nice.
The keyless chuck is also nice. It is an easy to pull system much like an air tool connection. Simply pull back on the outer ring and insert the bit. Done! Every bit held firmly. Nothing slipped.
My only concern is the battery charger doesn't seem very heavy duty. I have only had to charge it a couple of times as the battery lasts. It worked well. I just don't feel confident in its durability.
Overall I like this drill a lot. I will recommend it to friends when they try to borrow my tools!
