Pros: Compact size.
Cons: No storage for bits. Ergonomics could be better.
My wife had an old electric screwdriver that finally gave out after many years of faithful service. It was quite a bit larger than this Black & Decker Li2000 and used much larger batteries. The Li2000 uses internal Lithium Ion batteries and the unit itself is quite compact.
The screwdriver comes essentially uncharged so it is recommended that you fully charge it before use for at least 16 hours. Each time the screwdriver is used, B&D recommends charging it back to full to ensure battery longevity.
Two hex-shank bits are included, a philips head and a flat head. Unfortunately there is no clip or storage receptacle on the screwdriver itself which I consider a pretty big omission. A sliding switch controls forward and reverse with a center position which is basically an off position. The same switch used to determine forward or reverse is also used to activate the screwdriver. You do so by pressing down on the switch. It's a bit inconvenient to operate the screwdriver this way and I would have preferred a more conventional finger operated trigger. This is not a variable-speed screwdriver. One speed is all you get. It does have the ability to lock down the screw-head so you can operate the screwdriver manually if you wish. It's nice to be able to put the final spin on a screw manually so you can judge how tight it is.
The screwdriver handle has 3-positions... straight, about 45 degrees and somewhere in between straight and 45 degrees.
It's a handy little screwdriver with some room for improvement but for the price, it's adequate.
