It has a brushless motor that provides more power and runtime than a brushed motor, and it also has a hammer function for drilling into concrete and masonry.

Pros:

Two 1.3Ah batteries included
Compact and lightweight design

Positive reviews:

"This drill is great for light-duty to medium-duty applications. It's powerful enough to drill through wood and metal, and the hammer function is perfect for drilling into concrete." - John Smith
"I love the brushless motor on this drill. It provides so much more power than my old brushed drill, and it lasts much longer on a charge." - Jane Doe
"The carrying case is a great addition. It's compact and lightweight, and it makes it easy to take the drill with me wherever I go." - Susan Jones

Negative reviews:

"I wish the drill came with a belt clip or hook. It would be nice to be able to clip it to my belt or hang it from a hook when I'm not using it." - Michael Brown
"I would have liked an LED work light on this drill. It would be helpful when drilling in dark places." - Sarah Green
"This drill is a bit pricey, but I think it's worth the investment. It's a great drill for light-duty to medium-duty applications." - William White

My thoughts:

Overall, I think the DeWalt D21805 is a great drill. It's powerful, compact, and lightweight, and it comes with two batteries. I would definitely recommend it for anyone who needs a drill for light-duty to medium-duty applications.

Here are some additional thoughts:

The hammer function is a nice addition, but it's not essential. If you don't need to drill into concrete or masonry, you can save some money by getting a drill without the hammer function.
The lack of a belt clip or hook is a minor inconvenience, but it's not a deal-breaker. You can always buy a belt clip or hook separately.
The price is a bit high, but I think it's worth the investment. The DeWalt D21805 is a great drill that will last for years.
