Checklist

If you're planning to buy a new electric shaver, here's what to consider.

Type of shaver

There are two main types of electric shavers: rotary and foil (also called oscillating).

Rotary shavers have cutters underneath circular heads. With foil shavers the bristles poke through holes in a curved metal foil and are sliced off by an oscillating blade. The foils are very thin and can easily be damaged if you drop the foil or press too hard while shaving.

Either system can give a good shave. Because rotary and foil types work differently, you may find your skin is irritated for a while if you switch from one type to the other.

Power options

Rechargeable shavers offer convenience. Most can be operated on the mains as well, but shaving with the cord is only meant to be a back-up measure, in case the battery runs out.

If you frequently use your shaver on the mains, hoping to save the battery, you can actually shorten its life. On more sophisticated models you'll also disrupt the "number of shaves left" function. You can switch to the cord if the shaver runs out of power halfway through a shave, but recharge the battery when you've finished.

Small battery-operated shavers are useful for travelling, but are not usually suitable for everyday use.

Batteries

Most models use either a Nickel metal hydride (NiMH) or a Lithium ion (Li-ion) rechargeable battery.

Ease of use

Choose a model that's easy to clean and comfortable to hold. If it has a separate blade for trimming beards and sideburns, make sure your view isn't obstructed when you use it.

Cleaning is easier and quicker if the shaver can be washed under a tap, rather than brushed out.

Wet shavers

If you feel that a lather gives a better shave, or you like to save time by shaving in the shower, look for a "wet and dry" shaver. These can't be used on mains power, and have a charging stand.

Washable models

Cleaning out electric shavers can be a messy and fiddly job. A "washable" shaver will be easy to clean, as you can just run it under the tap, but is not intended for wet shaves.

Travel case

A pouch is easier to pack than a hard case when you're travelling. If your model has a charging stand or power pack, make sure it will fit into the travel case.

Also handy for travelling shavers: a travel lock (it ensures the power switch remains "off"), and a shaving head cover to protect the foil or cutters.

Indicators

A rechargeable shaver should warn you when it is about to run out of power. It's also handy to have a charging light (so you can be sure you've plugged it in properly), and a more precise display of the charge level. Other indicators may include a light to warn you that the foil or cutters need replacing, or the shaver needs cleaning.

Extra features

A docking station can provide a convenient base to recharge your shaver and can also incorporate a cleaning solution – but our triallists found them slow to clean and unnecessary.

Electric vs disposable

How does an electric shaver measure up to a disposable razor?

Pros

• Convenient: Electric shavers are quick – and you don't need to bother with shaving gel or foam.
• Portable: Most shavers come with a travel pouch. Charge them up before leaving home, and they'll stay charged for a week's worth of shaving.
• Easy to use: Most shavers come with a moustache trimmer, some wash themselves, and others dispense gel. Electric shavers are less likely to bite than a razor blade: they're great for those who have dexterity problems.
   

Cons

• Maintenance: Foil shavers need new foils every 6 to10 months and new cutters every other year (it depends on the thickness of your beard). Rotary shavers need new heads every 2 to 4 years.
