The only Kobalt tools I have are a tire fill/pressure gauge (2nd one) which doesn't measure accurately and a set of pliers with big think rubber grips which I hate. I'll take Craftsman tools any day. Just about all my Craftsman tools are 70's-80's vintage and I doubt I'll need to replace any of them.
I've got a similar issue with the tire fill/pressure gauge, seems mine is nearly 10PSI off. I've since bought a Slime branded one that goes up to ~65PSI (I believe?) that measures far more accurately when checked against others.
With that said, I'm a big fan of the Taiwan Kobalt ratchets/sockets. I don't trust the India CoO wrenches they've been stocking lately. For the money, the Tekton ones are a much better buy, and within about $5 of the Kobalt ones. I've got a Taiwan-made 72-tooth Kobalt ratchet that's been good to me for over a decade, and more recently picked up a 90-tooth to try out, alongside the Tekton 90-tooth. The Tekton is by far the best of the three, but none of them are what I would consider awful.
It'd be nice to see Kobalt products improve, one would imagine that it wouldn't be too difficult to have the same supplier Tekton is using for the Taiwanese tools produce them for Kobalt.
As a whole, I'd own more Tekton if it were available in a retail location close to me (central PA), but as my options are limited and I like to be able to hold tools ahead of purchasing them, I've been buying Kobalt and HF for quite a while and not been terribly disappointed for the most part.
