Welcome Visitor! Please take a few seconds and 
I'll agree with the others....my no-slip is very smooth. Much more than what some people claim. Im not sure what type of lunchbox locker theyre using, but the no-slip is absolutely fine with daily drivers and city street driving. The obvious applies of course, as with a locker if you try to accelerate too much in a turn you'll bark the tires, or depending on speed, experience understeer...but there isnt much racheting action or clunking at all.
