Expected More...
I had a Norelco triple header with height adjustment for eight years.  It gave a close shave, but I had to work at it, especially the neck area.  I got my money's worth and more given the trouble free service and I didn't have to replace the blades.  The 8140XL is performing the same in terms of quality of shave and speed.  I expected more given the hype of the triple rows of blades w/in the each of the three heads.  Water cleaning works well.  Much quieter than previous one.  I get 3 to 4 shaves from a charge.  The 8150 model offers a "need to recharge" light.  The 8140 does not, and it just stops w/o warning so better have the charger handy.  Hard to believe that Norelco can justify a higher price just for the convenience of a charge warning light.
