Thanks for your input. In was thinking of picking some up just to check them out. I have several Knipex plier wrenches, which are great, and haven't had a need for an adjustable since.
I am not a big fan of adjustable but i bought the 6" snap on because it opened up to 22mm so it works great for getting o2 sensors after you brake them loose. I used mine quite a bit and so far i didn't notice any chrome chipping.
