Reviewers say the Braun Mobile Shave M-90 gives a surprisingly close shave, considering that it's powered by AA batteries. Its twist-open cap protects the foil and also serves as an extension for the handle. The Mobile Shave M-90 is a little on the loud side and won't always replace a full-size shaver -- especially if you have a coarse beard -- but reviewers say it's still great for touch-ups and shaving on the go.
Surprisingly decent performance. Although most users say they like the M-90's shave and consider it an exceptional value for the money, we did find a fair number of complaints from both Drugstore.com and Amazon.com users that this razor pinches and pulls, especially when you're shaving difficult contours like your chin and neck.
In a video review for Electric-Shaver-Guide.com, the reviewer does not recommend this model because it struggled to cut through one and two days' worth of beard growth. However, he notes that it might do better for those who don't have to shave every day.
Owners also seem bemused by the placement of the M-90's trimmer, which sticks out at a right angle to the shaving foil, although they say it can help reduce discomfort when shaving your chin or neck.
Quirky, but useful. Users say the Braun Mobile Shave M-90's best features are its compact convenience and travel capability -- just pop two AA batteries in and you're ready to shave. Reviewers say two AA batteries can last for more than two weeks of regular shaving.
Users report that the Mobile Shave M-90 feels pretty well built (especially considering the price), although one Amazon.com reviewer worries that he might break the protruding trimmer when he tries to extend or retract it. Once you're done shaving, you can pop the foil off and let it dry separately from the rest of the shaver, which is washable.
Opinions are split on whether the cap, which protects the shaving, is helpful or just "weird." Other than that, the biggest usability complaint we found was a tendency for shavings to spill everywhere.
Acceptably loud. A smattering of users, mostly at Amazon.com, say the Braun Mobile Shave M-90 is a little on the loud side. The extra volume and abrasive sound quality is obvious in a video review from Electric-Shaver-Guide.com on YouTube. Still, nobody seems to mind too much; as one Amazon.com user who remarks on the noise also points out, the M-90 shaves quickly enough that he can put it away after just a couple of minutes.
Standard, with a low replacement cost. The Braun Mobile Shave M-90 comes with a two-year warranty and a 60-day money-back guarantee. Users report an estimated new foil cost of about $13 -- roughly half the cost of buying a new M-90. Buying a new M-90 still costs less than buying replacement foils or heads for other full-size razors.
On the other hand, we found quite a few reports that men keep a disposable razor on hand for dealing with stray or curling hairs that the M-90 missed; you might want to factor in that additional cost. You'll also have to pay for AA batteries, although some consumers cut cost and waste by using rechargeable batteries.
A reviewer with Electric-Shaver-Guide.com reviews the M-90's features and tries it out, offering about six minutes of video commentary about how well it works. He notes that it does well on the cheek and lip area, but has a tough time over the neck and chin.
