I’ve used one, and it actually is pretty good. For comparison, I have a Megapro Automotive (211R1C36RD) screwdriver. I like the ratchet and shaft knurling of the LTT more, but the smaller bits are a bit annoying (though the smaller handle size because of them is nice). Overall, it’s not a bad screwdriver, and even though it is too expensive for me, it’s another good product option in case other brands’ tools don’t fit someone’s needs.
To be clear, LTT is plenty problematic, but I don’t think “making a screwdriver” is one of their problems.
