Your QL1 statement is confusing. You imply the mdvs work without flp,
but don't say. "I'm not saying they are faulty"!
Also describe completely what happens with mdvs on -all- machines.
ie do they spin at all, and does the spinning sound smooth.
It is all a bit vague.
BTW often the roller on mdvs rides up and touches the case top.
