Well I finally had a nice day, where I could try out my cheapo Black and Decker 18 volt cordless drill. I used it to repair some metal roofing on one of my barns and to put up my winter plastic window covers on my goat barn. I gave it some pretty heavy use, using it to drive in screws through sheet metal into wood and very heavy plastic into wood. I then used it to repair some fencing. All in all, I used it pretty heavily for about 2 hours, and amazingly it worked better than I expected. It worked as well as any cordless drill I've owned.
Now, I'm not claiming it's as well built as other brands, but it had the power to do what I needed, and the battery held up fine for it's first day of hard use. The drill will be used often, but not as hard as I used it today. Considering that none of my other cordless 18 volt drills lasted more than 2 years (DeWalt, Hitachi, Porter Cable or Bosch), if this drill lasts a year, I"ll be very happy, considering that I spent a whole $25 on it.
I'll post ocassional updates on my cheapo drill use. But after using it occasionally for a few weeks and using it one day pretty hard, I've yet to have to recharge the battery, either. I'm just soooo sick of paying $100 to several hundred to only have to replace my drill every other year.
