we own most of these craftsman 19.2 v tools shown here.most of them are the original set- the ones that came out first not the newer ones. although we have the newer charger and i really like that because it tells you if the batteries are bad. they are heavy duty and can take a beating- they are a bit heavy-i hear the newer ones are lighter. a must have for the handyman or handywoman in the house. i like the better than any other brand of tool- i know craftsman will stand behind any product it makes. they work great the overall battery life seems to last for a few years. i am now just replacing the batteries we have been using since 2008 or earlier. these are great tools to just grab and go, i believe that this set comes with a hard case to keep the tools in which is really nice. like i said i bought most of mine seperatly and most of those came with their own cases too. the one tool that i was not impressed with was the flashlight-worked great for some time then when we changed the light bulb the flashlight stopped working-almost like it burt up or something. overall these tools will not disappoint you at all and are worth the investment.
