Summarize the following:
Whether you want to save time, avoid mess, or get a close shave without irritating your skin, there are basically two types of electric shaver to use: rotary and foil. Rotary shavers utilize a revolving motion that guarantees a closer shave. This is a very popular choice because it doesn’t pull hair and provides a comfortable shave.  The three rotating mechanisms of a rotary shaver can help with hard to reach areas. Flexibility can depend on the brand so do your research to accommodate the contours of your face. Titanium blades that form part of the rotary mechanism aid in painless shaving.  A foil shaver has oscillating blades behind steel foils that lifts the hair out of the face as opposed to cutting it. These electric shavers have 3 to 4 blades and more blades means a reduced shaving time but can also be more noisy . The large head allows you to cover more area so this choice may be right for you if you want a quick and efficient shave. Foil shavers need the foil replaced every 1 -2 years depending on the toughness of your stubble. If you end up pressing harder to get a decent shave, chances are that you forgot to change the foil.  Rotary blades needs to be replaced once a year.  Skin irritation is another sign that you need to change the foil. Don’t throw away the manual as details of how to replace parts and valuable manufacturer contact information will become invaluable the longer your keep your shaver. Understand that each shaver utilizes a different method to remove hair so optimize your shave by moving in a supplementary direction.  When using a rotary shaver, make small circular motions  with the shaver head on your face but remember not to press hard or go over the same spot repeatedly to avoid irritation.  Foil shavers work best when you shave with back-and-forth strokes. Debris can easily build up, especially if you have thick facial hair so be sure to regularly clean your electric razor. Do not bang your shavers or use tools that aren't specific to cleaning shavers.  Foil shavers by Braun, Panasonic or Remington can be cleaned by lifting the head frame off and gently brushing out the whiskers from the under side with the cleaning brush supplied by the manufacturer. Do not touch the screen because it is very fragile.  Philips rotary head shavers can be cleaned by lifting off the razor head assembly and brushing out the under side of the three cutters and the razor chamber. Don’t tap the heads on the sink as it may dent or damage the precision-made combs.  Remove each cutter and comb the retaining plate of your rotary shaver every other month, or more if you have thick or fast growing hair, by brushing the whiskers from the cutters and soaking them in liquid cleaner and lubricate.

Summary:
Identify what factors are most important to your shave. Replace your blades periodically. Shave with proper technique. Keep your shaver clean.
