Unlike other trimmers, Panasonic ER-GB40-S allows you to trim your hair, beards and body hairs. It has 19 adjustment settings which enable you to adjust according to your desired lengths. The settings vary from 1mm-10mm and an increment of 0.5mm between each setting. This gives you a wide range of choices to select from according to your desired length of trimming. It also has a zero setting which you get after you have removed the guard. This enables you to shave directly with the blade to give you a very close and stubble look. You can use it either as a dry or wet trimmer.


It is very easy to maintain since you just need to oil it once or twice in a week. In addition, it is easy to clean and all you need to do is to clean the head of the trimmer after every use.  It has an inlet at the back of the body which allows water to pass through and come out under the blade when cleaning. This inlet also allows excess hair to pass through. If you want to perform an in depth cleaning, you can just remove the blade and rinse. The fact that this trimmer is waterproof makes it easy to clean. All you need to do is to ensure it is completely dry before assembling it together.

  • Put it on the charging dock after use to extend the life of the battery.

  • Check the batteries regularly to ensure that they are in good condition.
  • Replace the blades at least once per year.


It uses a Nickel Metal battery which is not as good as compared to Lithium Ion battery. You can use it for 50 minutes when fully charged and takes about 15-20hours to be fully charged. The problem is that it is not easy to know when the battery is fully charged because it does not have an indicator. It only displays a red indicator when charging and the best thing you can do is to allow it charge for at least fifteen hours.
