It's a great idea and should be a five star tool because of its wide range of uses combined with great portability. Unfortunately, it just doesn't hold up over time. I bought mine a couple years ago through Amazon (long enough to be past its warranty) and it won't hold a charge anymore. Since there's no way to replace the battery, it's junk. For the first year maybe, it worked very well - though I never used it that hard or all that frequently. Then it started cutting out every once in a while, requiring a restart only to have it cut off again when any pressure was applied. Then it stopped working altogether.
I'm willing to try the 8000 model because I got to used to a cordless tool, so we'll see if that one holds up a little better. The good news is, that one has a replaceable battery so I have more confidence in it than I do with this one. The pistol grip is a nice feature, but I'm more than willing to sacrifice that for a tool that might actually stick around for a while.
