Question 1

This is not doing anything, and I am confused by all the good ratings.  It didn't cut any of the hair - am I doing something wrong???

Accepted Answer

My husband has very very very thick facial hair, and he says he has to use it every day or the hair gets a bit too long for this shaver to give him a close shave without making multiple passes over the hair (which can cause skin irritation I believe). He uses this as his "I-don't-have-time-to-shave-before-I-run-out-the-door-for-work" back-up shaver, and uses it in his car in the parking lot (or in his office) before he starts the workday. He has also said that the foil on this razor isn't on par with Braun's standard foils, and that may be part of the issue with it not working as well. However, for the price, and not needing a charger, he continually states it serves its purpose. His regular routine involves using the clippers (that he uses for haircuts) to get his beard down very short, then using a safety razor (rather than regular disposable) to smooth it all out. Like I said, thick hair, hard to take care of. I have seen him though, on occasion, just use the clippers, then clean it all up with the Mobile Shaver. Hope this helps...

Question 2

How long do the batteries last?

Accepted Answer

With eneloops some 4 hours. Primary Alkalines have an initial voltage around 1.5V, but with use this drops to 1V or less. I understand that electric motors rev faster at higher voltage - more power? So you might have a faster shave initially with a fresh Alki - but a solid 1.25V from robust eneloops might be preferable overall. If co$t is no object one could use long lasting primary 1.8V lithiums - both high power & runtime.  I have experimented using a safe rechargeable 3.2V LiFePO4 battery. Lightweight with a Dummy second cell, this offers a solid high voltage for power, but reduced runtime. With no more than 60 minutes expected, I put in a freshly charged LiFe cell weekly.

Question 3

Can someone explain to me why the 370 replacement foil is $15, but this whole trimmer is $22? I feel like something is off here.

Accepted Answer

Unfortunately the cost of the replacement parts for the battery operated shavers is almost the cost of a whole unit.

Question 4

Is the side-trimmer selectable or always on?

Accepted Answer

Selectable. Trimmer is activated when pushed out of its slot on the backside of the shaver.
