Sturdy compact screwdriver
Great little screwdriver with plenty of power and can take a beating using it. Small and compact, fits in your pocket. I bought a second one because I was so impressed
User
great tool
This is probably my first review for anything on amazon. I needed a lightweight tool to disassemble a small warehouse full of industrial shelving, and if you know what that is you know how many screws and nuts need to be taken apart. The torque on this tool is very strong or can be locked in the middle position.I don't think I could have done this with my larger cordless drill as this was smaller and light but very strong and keeps a good charge.It took a lot of abuse and quite a few drops. The only thing I can't say is how it will hold up over a longer period ,but for now I can not recommend more highly from my experience.

Powerful In A Small Package
Husband said it was "a little too powerful" for our task. This is wonderful for small tasks around the house. Light in weight. We have 2 more Hammerhead products to try as well. So far, good for pricing. Hopefully it lasts for a few tasks.

Finally my own “drill”
Whenever I don’t have the strength in my hands to do a task, my husband gets out his cordless drill that weighs way too much for my small hands. I needed to assemble a piece of furniture and didn’t want him to have to do it so I bought myself this little tool based on the reviews and I love it. It is hidden away where he can’t find it so I don’t have to wonder where he left it. His is never charged when it’s needed and too heavy for me to handle anyway. I love how lightweight and compact this is and it works like a charm.

Good helper
Great drill.Saves time from hand drilling.

Work surprisingly good
This is the perfect size for tucking away into a work bag. Keeps a charge for a good bit. I like it for the cost because if I accidentally leave it behind I'm not crying about it. However, with that being said, I'm surprised on how strong and durable it is for the money.

Over tighten screws
This is what you need instead of using the impact and over-tighten the screws. I've had so many messed up screws because the previous guy didn't know how to use the gun, so I use this in so many places. Last kinda long too.

Weight
It is perfectly fits in my small hands, heavy man drills are heavy after awhile. Is nice, but where the reverse and forward button is placed is always shifting for my hand. Holding the handle part. I do wish it worked with a charging cord, I use it for word with 2’screw bands . Holds a nice charge
User
Great value
Bought it for its light weight, love it for its ergonomic design. Battery life is longer than expected for a 4V. Able to do the entire house recepticles and switches replacement with one charge and still got juice left. Was supprise to see how strong the torque is for such a small drill. Like it even more when I was able to stop then use it as a hand driver for the last feel torque

Excelente funcionamiento
Tiene la fuerza suficiente para utilizarlo en MDF y triplay con el adaptador para broca es lento pero hace el agujero
User
Very good value for the money.. fully recommend
Useful 100%, fully charged first time and worked well when using for the full day and battery still running... very light, and nice to have the lighting to help you see in dark places..
User
Quick and Compact.
PROS:Battery life is fairly good, I have only had to charged it once since I received it and began using it right away for a few days straight. It gets the job done quickly and efficiently. Fits in my pocket if I need to quickly use both hands to pick up or reposition something. Overall worth the price and great for small projects around the house like furniture assembly or disassembly.CONS:No battery life indicator, really hard to use against tight corners or walls because of reassessed mount and bulkyness.SUGGESTED IMPROVEMENTS:LED light might be more useful if it was on either side instead of under. Extended the mount piece an inch or 2, or ship product with one of those flexible snake extensions to be able to use it within tight or deep recesssed groves otherwise one will have make a seprate purchase.
