I hate 'em. They're marketed as the next great thing but I simply can't stand spline drive. Does it work? Sure, most of the time. Is it better? I'd say absolutely not. It's more likely to try to "ride over" and get stuck on a fastener, and unless you have REALLY good, FULL engagement, it's much more likely to damage fasteners.
The Kabos are actually quite thin and flex easily. This means on stubborn stuff they just deflect. The side button is actually easy to bump.
I wish I could afford (justify, really) the Snappys, but the price is stratospheric.
The middle ground is Matco. Still spline, but a MUCH thicker beam, and more traditional reversing lever on the back. I actually REALLY like my Matcos, but still wish for 12pt -- and I only have the metrics. Every time I need fractional and have to reach for my Carlyle (Kabo) I make sad face.
I think someone like HF could make a small fortune if they perfected this space. Everyone either rebadges the Kabos or tool truck stuff is beyond the common man.
We have the technology, it's not hard:
1) thicker beams than Kabo
2) 12 pt
3) reversing lever on back
4) keep the SHORT extended drive on one side, it's awesome for things like reaching into tensioner pulleys
5) I'd like to see metric and fractional, but must admit sales of the latter may be lackluster
6) ICON pricing but not SnapOn pricing $$
I don't think this is too much to ask, and most of it is just combining pieces already in manufacture.
