I have the non-LED flashlight, was better for the price. I can tell you for sure that it beats having no light in the dark, and with the magnet on the back you can position it fairly well. My LED bulbs should arrive soon so I'll have an LED light out of it anyway for less than HD wants.
I have the non fuel hammer drill & 1/4 hex impact. Both do well though I have 18v tools for when i need real power. The hackzall is amazing, when coupled with the
kobalt kit its even better. I cleaned the grill with the wire brush last night. files, file cleaner, wire brush its not too much like a corded recip or the 18v is, its just right in a lot of cases. LOT less fatigue.
As a saw, I mostly use it for household maintenance & demo though. drywall, wood, and especially with a pruning blade its pretty handy. I've used it with a metal blade but not much, I have an 18v and a corded recip they're better suited.
I upgraded from another 12v kit that also had an oscillator & dremel tool with that kit, these are basically the same but the other parts are all better enough that it was worth basically buying the same tool again. My M12 kit is all still pretty new but almost all I've done with it has been either on cars or with scrap metal. They hold up pretty well when you push them a little harder than you should.
