I have to weigh in on this one, I broke down last year and bought the dewalt combo drill,driver, sawzaw and light 18v It was a price issue. I am happy with it. I built my whole deck with it. The driver is the (POOP!) LOL didn't want to get in trouble. The key is, I know on dewalt the charger never shuts off. So after the light quits flashing you need to remove batteries then. Don't leave on charger. If you have trouble like me remembering, use a timer. The batteries loose a lot of life if you just leave on the charger all the time. Now as far as the new Ion batteries I don't know anything on them.
