Out of the three razor I'll never ever ever let go, two are injectors. The Bunny V3 and the Eversharp Fashion razor. So I don't find them boring at all.I have a Neo II which I used for a very quick shave until I discovered injectors.
Tomorrow/today I'll try it with the pivot lock off.
I find injectors highly effective but a bit boring so I see where you're coming from.
The third is a 1912
