Bought for homework. Completely satisfied. It is a pleasure to work. Its pros: It lies perfectly in the hand, the geometry of the battery allows you to climb where the other gets in the way. Sufficient battery life, fast charging. The fact that a screwdriver cannot be put on a battery is IMHO even for the better, since you cannot drop a screwdriver invested in a holster by accidentally hooking it with your elbow. Cons below: A sharp stop when the button is released is very annoying (sound) in drilling mode. You have to release the button smoothly (I got used to it in a month). It is advisable for the manufacturer to move the direction of the beam of the flashlight closer to the jaws of the cartridge.
