My wife and I have given this Ryobi Cordless Drill a workout over the last few years with many remodeling jobs, and it is still going strong. We bought it at Home Depot for around $90. The drill came with 2 battery packs, a 1-hr. charger, 2 screwdriver bits and a plastic carrying case. This is a very heavy-duty piece of equipment and is not a lightweight. I am a big guy and don't have much trouble with the weight of it, but it can get heavy for my wife when she uses it for a long period of time.
The drill bits and screwdriver bits are easily changed by hand with the keyless chuck, and there is a handy clip on the top of the drill to store two screwdriver bits. The drill can be set to either high or low speed with a switch on top of the drill, and the variable speed switch lets you control the speed with the trigger pressure. The switch can also be set to off when not in use. There is a built in level, which helps me drill or screw on the straight and narrow.
The batteries will last about a half hour of continuous use before you have to change it. Having the second battery, means I can always have a battery set to go when the other one has died. It usually only takes about an hour to charge a battery back to full charge.
I wouldn't recommend this for a big job like building a deck where you have to drill hundreds of screws, but for most smaller jobs this will do the job.
