Metal drill handle/body = professional look/feel. Great battery. Easy to use. Good power.
This is quite an impressive battery powered nail drill. It's a very credible device, with a motor capable of 35000rpm.  So, it has the power. Visually, it has an attractive design with a professional/industrial aspect. The metallic body of the drill body exhibits durability and sturdiness.<br />The top segment of the drill handle twists, with a marker that indicates position respective to the locked/unlocked icons. Obviously, these position are for removing/inserting drill bits. Make sure that after inserting the selected drill bit, the top is twisted and engaged in the locked position.<br />The battery pack also doubles as the control module for the drill. The silvery knob (plastic) turns on the power and gives access to the variable speed settings.  When powered, the display shows the direction of rotation, F/R, and the speed. The button below the display allows the user to change the direction of drill rotation. Under that button, marked Status,  toggles the display from direction and speed to the current power status of the battery. (In the attached photo, P91 indicates Power 91%)<br />The controls are easy to understand, and manage. There's a belt clip on the back of the battery pack/control module. You can opt to have it affixed to a belt or pocket, or place the pack on the table where you can easily make adjustments.<br />in terms of battery efficiency, it takes 2 - 3 hours to fully charge a depleted battery, while affording up to 20 hours of operating time. Actual time will depend on speed and application load. I would expect actual real time use to realize over 10 hours of operation. The charging:operating time ratio is very impressive.<br />I've seen/used prosumer level nail drills, very similar to this product. Those units can range in prices over $100.  Based on comparative costs, this is priced very well in the market genre. In other words, it's a very good value for the features and quality.<br />Based on these considerations, this portable nail drill earns a 4.5 - 4.75 star rating, with a very high level recommendation.
