Surprisingly powerful for such a small drill. Plastic is glassfiber-reinforced, although no indication of what percentage. The molding is quite bad.The overmolding is reasonably anchored. Battery consists of no-name 18650's claiming 1300mAH's per. All the balancing is done inside the battery; only + and - go to the drill. It outputs a little less than 21 volts when full. No conformal coating on the PCB in the battery. It charges fast. It has a decent switch with a heatsink for the MOSFETS and has speed control. The motor is just some of the shelf brushed DC motor with non-replacable brushes. The gears are powdered metal, the grease doesn't seem to be too bad. The chuck is unbranded and rusts quickly. The hammering action is pretty much useless. Cons: the connection between the motor and the gearbox is pretty weak, just two little plastic notches. It might fail after a fall. The carbon brushes are not replaceable, are a little too small and therefore get very hot very quickly. They spark at spinup and at spindown. If this drill fails, it is most likely due to molten brushholders. Pro's: for the price, this is unbeatable. It's pretty strong as well. I'm curious to see how long it lasts.
