I've had chance to try mine a couple of times. Not in the field, in laboratory conditions (the garage) and i like them.
After using soft - touch ones I wasn't sure about the hard plastic but you get used to it. It's easier to keep clean. The tip identifier on the handle is nice and big and much easier to see than the ones I use now. The handle neck would be better with six sides as opposed to the eight, which would make it easier to get a spanner on for those rare occasions when you need extra torque.
The slimline blade is a nice feature, with the insulation let into the shaft. I like the black exposed metal tip which is well machined and appears hard enough to resist wear without being too brittle.
I agree with handy sparks that at 110mm they are not the stubbiest of stubbies.
A quick search didn't reveal anything comparable so I reckon CK have cornered the market a bit here. So if your looking for a stubby these won't disappoint.
As we know from the CK video, these drivers can talk so I think it would be cruel to consign them to a retired old codger's tool box. It would probably be like Michael McIntyre's spice jars . So I'll pass them on to my nephew who is working on new build multi screen cinemas across the country and can make much better use of them than me.
