This is the most basic of hand held power drills. It is a simple electric drill with one speed and one direction. It is mainly good for drilling holes in wood, metal, plastic, and soft metals. It is not the ideal choice of drill to use for applications such as driving screws. Since the speed is not variable and the drill only operates at a higher RPM, you would likely either strip the screw head or snap the head off the screw if you tried. You will not likely find many of these around today as their uses are rather limited.
If you would rather prefer an entry-level dSLR, then you better get Nikon's D3100. It offers fast performance, superior image quality, and unparalleled control.

Lithium mines Ontario-Ion batteries are revolutionary in fact, not just simply better than Ni-Cd. They don't have memory effect, which means you can easily use them a little and then partially recharge them just to discharge them to a certain percentage of their capacity other than zero. They like partial charges and discharges better than full ones, but memory effect is not something you should be aware of.
Memory effect will reduce the life of a battery. Modern Lithium-ion batteries do not suffer from memory effect, although it does occur in Nickel-Metal Hydride (NiMH) units when charged from levels other than 0% of battery capacity. If the (NiMH) unit was fully charged when initially at say 20% capacity, the resulting available capacity would only be 80% of the factory original. Of course every time you charged the battery, the total available capacity would reduce and eventually your mobile phone would prove to be increasingly useless. Nearly all new electronic devices are now powered by Lithium batteries. You should always condition your (NiMH) battery from new.
Recharge the battery to full again and repeat the above steps a few more times. This will allow you to use the battery for a longer time and you can do this no more than once a month. Replacement batteries can be expensive and stretching out their use when you are on a budget can help.
