The intelligent, time-tested design of a hammer provides a long handle both to increase reach and to multiply the user's power through rotational force. The handle also helps to mitigate some of the impact shock.
If you remove all of those advantages, then you get the Hammer Fist. This tool was invented by a toy/product designer, and was apparently intended as an earnest effort.
Here's how you're meant to use it:

I just don't know where to begin. It's not as if the compact design is useful in tight spaces; your arm is still required to hold the thing, and if you can reach your arm into a space, you can also reach a standard hammer into that space. The increased surface area of the striking face seems like a recipe for overstrikes and marring, should you hit the nail anything less than dead perpendicular. With no handle to serve as a force multiplier, it's just you and your muscles. It also seems the impact shocks would be transmitted more directly into your finger joints and wrist.
The description says the tool can pull nails, but again you've got decreased leverage from the absence of a handle.
That being said, I'm not a contractor and don't earn my living hammering nails. I was also shocked to see this tool is carried by Home Depot, which at least in my region services working contractors and is generally not in the business of offering items that don't sell. So it's entirely possible this tool has an advantage I'm ignorant of. I'm open to learning what that is, so if the benefits are obvious to you, please do share it in the comments.
