I have it and while I don't mind it, looking back I probably wouldn't buy it again.
Originally, I had no drill bits or anything, so I figured this would be perfect to get me on my feet with my new Craftsman drill/driver combo. A few months later and I already had to buy a complete set of drill bits because the ones in that set weren't cutting it (no pun intended). Now all I really use it for is the Phillips and socket adapters.
I guess it really spends on what you are using it for. To me, there's a lot of it I don't see myself ever using.
its only $15 that is not a bad price even if you really only need the insert bits, and never need/use the actual drill bits.
I have an older C-man insert bit set and love it, it is all USA made, and it's only a 30 piece set and I think it ran me $25 nearly 10 years ago, but I have used it a lot, and it has earned its keep.
This is techtronic industries stuff (says it on the site). Their brands include milwaukee and ryobi. So probably probably similar to those offerings (bit wise) which ain't too bad.
