I believe it would depend somewhat on how easily the knobs turn.
The power knob on my VXII is pretty danged tight, enough so I sent it in. They disassembled it lubed it sent it back with a note saying that's the way it is supposed to be. I'm sure not worried about that thing changing on its own accord.
I picked up a new Nikon M223 1-4 last weekend. I sure hope it isn't an issue. Planned on a like type Leupold AR 1-4, last minute I decided the turrets might be nice, and brought the Nikon home. Hope it was the right choice, I will soon know.
