I know everybody else raves about the 18v tools that are available. I have been a hold out for no other reason than the extra weight the extra voltage brings with it. Having two battery powered drills has always suited the way I work so, when I gave one of my drills to my son, I needed another. Looking at the prices, I decided it made more sense to buy the kit that came with two batteries, a drill, a circular saw, flashlight, and a sander.
The saw, used for what it was designed for, does a fine job. It is a small saw and well suited for thinner stuff. It will cut heavier stuff but battery life drops off quick. The flashlight is handy and I use it once in a while but mostly it gathers dust. The sander looks pretty good for detail work but, I haven't tried it as yet. The workhorse in my shop is the drill, normally used for running screws. The drill in the set is indeed heavier than the 14.4's I have been using. The balance is a tad better so even with the extra weight, it isn't the arm killer I expected. I've run a hand full of two inch screws and it hasn't been bothered with the effort. The finish on the drill chuck jaws isn't as good as my previous drills yet appears to hold just fine. Keep in mind this is a HAND DRILL, ultra precision is not done with a hand drill, a drill press is the better choice if you REALLY need that kind of precision. With that said, drilled holes are fine, driving screws is excellent and the clutch for setting the amount of torque applied works just fine.
The kit over all in my opinion is a good buy. You get more than what you pay for and the tools work as they were meant to. For the average household bashing stuff that folks do, this tool kit will get the job done with no problems.
I have numerous Ryobi tools in my shop and have gotten good service from them. They tend to be reasonably priced and hold up well. They are not the tools of choice for the 'pro's' but they do fine for me. I do a fair amount of tool abuse in my shop during the course of a day. I don't drop them from the roof or run over them with my truck, I use them as intended and I squeeze all I can out of them.
