Common reasons you might choose a rotary shaver include:
Noise is a deal-breaker. Rotary shavers tend to be quieter than foil models.
You like to go a while between shaves. Experts say that rotary models may handle longer hairs better than foil models do.
You have a hard time shaving along contours. Many say that the multiple, independently rotating shaving heads on a rotary model do a better job of handling difficult contours (like the chin and neck) than foil models do.
You're used to rotary models. If you're already used to the circular motions of shaving with a rotary electric razor, you might not want to teach yourself the long, straight strokes required of a foil shaver.
Common reasons for selecting foil models include:
A close shave is of the utmost importance. Experts say that, in general, foil shavers get you a little closer to the feel of shaving with a blade. In addition, experts recommend shaving against the direction of your hair growth when you're using a foil shaver.
You're used to shaving with a disposable razor. The long, straight strokes of a foil shaver resemble the same movements you'd make with a disposable razor.
Do you need an electric razor with wet/dry capabilities? If you know you have very sensitive skin or that dry shaving can irritate your skin, experts recommend trying a wet/dry model.
Some men prefer shaving in the shower, or just after a shower, for the sake of expediency or comfort. If this is you, keep in mind that wet/dry capability doesn't automatically mean an electric shaver is fully immersible or waterproof. Select a model that's specifically designed for use in the shower. Check the documentation to be sure; some models display a shower symbol on the shaver casing, too.
In theory, electric shavers are less expensive in the long run than constantly replacing disposable razors. But is that really true? According to figures published at Razorpedia.com, shaving with disposable razors will cost you about $111 a year. The electric shavers in this report range from $100 to $250 in street price, so in a perfect world they'd pay for themselves after a year or two of not having to buy disposable shavers.
However, you must factor in the cost of maintaining your electric shaver. Yearly upkeep typically costs between $50 and $80 to replace the cutting blades and foil, and if your shaver has a cleaning stand you'll also have to pay for refill cleaning cartridges. That means you'd need to keep an electric shaver anywhere from two to four years to break even with the cost of disposable razors. If you have a cleaning station for your shaver, the cost of cleaning cartridges -- anywhere from about $40 a year to a whopping estimated cost of $180 a year for the Philips Norelco SensoTouch 3D 1280XCC's Jet Clean cartridges -- may keep you from breaking even at all.
We're excluding battery-powered travel shavers from this figure; at about $20 apiece they're so inexpensive that it makes sense to buy a new shaver every year instead of replacing the blades.
The bottom line? We've taken the cost of ownership into account when earmarking the best electric shavers in this report. Despite their initially high price tags, the Braun Series 7 shavers (Est. $170 to $200) have one of the lowest costs of ownership -- $20 to $32 per year if you don't need refill cartridges for a cleaning stand -- which makes them a smart investment overall.
