Review (3/5): We'll see how long this lasts...
Provides a decent shave, particularly after the beard has been moistened as it is immediately after a shower. The question is, for how long, considering the flimsy construction of some components and the already below-specified battery life.
Things they don't describe in the mostly worthless manual:
The charging indicator is a steady red AC plug symbol.
The LCD indication at full charge is 99. A RED (not a far more intuitive GREEN) battery full symbol is shown at when the charge reaches 99.
A low battery is indicated by a flashing red AC plug symbol when the charge number on the LCD reaches 10.
Charge time was tested and found to be 82 minutes. The manual claims 60 to 90 minutes, so they got that right.
Use time is specified in the manual as 50 to 60 minutes. The run time was tested and found to be only 30 minutes in 5 minute on, five minute off intervals, just free running and not being used to shave which should further reduce the run time slightly.
The charge indicator was at 52 after 25 minutes and then rapidly dropped from that to 10 only five minutes later causing the low battery indicator to flash, so I would definitely NOT trust the charge indicator to be an accurate indication of how much shaving time you have left. They are apparently not calculating percent charge remaining and displaying it on the LCD, they are simply and far less usefully displaying percent battery VOLTAGE which drops off rapidly at what is called the battery's discharge "knee." A cheap route to take revealing that the LCD display is nothing more useful than a gimmick.
The manual states that the razor should be unplugged from the charger (this razor package does not come with an AC to USB charge adapter) when the charge number reaches 99, so I suspect this charger might not have an intelligent charger which stops the battery charge process at full charge to avoid battery damage over the long term. So, I will not put this razor on charge and just forget about it until my next shave like I can with my Norelco with its intelligent charge system.
Other information:
The space under the heads which catches the beard shavings is very small. Cleaning often will be a must. We'll see how the hinge and head locking mechanism hold up.
When opening the shaving head to clean, put a finger on it to slow its opening, otherwise it will rapidly flip open and if a razor element isn't locked into its place by its flimsy and not very intuitive to correctly replace locking ring, as it wasn't in my case, the razor element and its parts will be vigorously projected into an alternate universe. Luckily, I found all of the parts. Had I been standing over a sink, some could easily have gone down the drain. We'll see how the razor element locking rings hold up.
