Review (4/5): Not quite top of the line, but very close
Norelco's website claims the 7775X to be their "top of the line" lotion-dispensing razor. This is true in all aspects but one: the choice of batteries. The manufacturer has opted to stick with Ni-Cad batteries. This is not necessarily bad (they still perform well), but the absence of smart trickle charging forces the user to "baby-sit" the charging process. This means no charge-and-forget scenarios; set a timer and unplug everything when it's done!
Other than that the unit is great. It's light, shaves close and comfortable (I guess those lotion-retaining, guide rings really work!), and can easily go over a week of daily use on a single charge. The status lights are a nice touch, but reminders to dispense lotion and rinse afterwards are redundant; especially for users already familiar with these wet razors.
All in all a good purchase to replace my Norelco 6735X, which lasted over three years before succumbing to dead [Ni-Cad] batteries...
