Yes I forgot to mention that Dennis.
You put me onto them when I was having the 'Flat Finish' problem.
I still use them often but I've found that a final buffing usually with the WHR mop and Menzerna M5 gives that extra bit of Lustre.
Incidentally do you wash your Micromesh sheets out when they look clogged? I did think about putting them in the ultrasonic to shake the clogging free
