I got an ML when they first were available. I have seen no difference in the vape, unless you set a curve with the software. Then, there is a difference.Well I put my ML away till my sleeve gets here then I will play somemore but don't want to get it messed up. I don't notice a major diff between my M's and the ML on Ti.
Is the difference good or bad? Depends on how you set the curve, Ha!
But in any 'factory' mode, no difference between the two.
The difference to me was the look and feel. I like the ML a bit more than the M.
My second has finally found its way to 'Out for delivery' status from the USPS. This one is actually a reship because the original one shipped for this order was an M class, and not even the right color.
In a couple of hours, I'll see if the online fates have smiled upon me this time.
