Dewalt has a great product line with the cordless 18v tools. The week spot of the entire line is the 18v battery. Replacement batteries dont last long enough for the price (I did however get a great deal buying 2 replacements here on amazon).It normally costs more for a replacement battery than it did to buy the tool. When buying cordless anything, keep the cost of replacement battery packs in mind. Sooner or later you will have to replace them. It just comes way too soon with these dewalt battery packs. It would be great if Dewalt would allow you to trade in your old battery for a discounted new battery.
