Panasonic ER-GB40-S Review

If you need a fully adjustable, lightweight trimmer that works in dry as well as wet conditions to ensure great skin just the way you want, the Panasonic ER-GB40-S is the product for you.


The incredible design of the trimmer features a blue-colored, rubberized grip that aids in comfortable use and control of the trimmer. On the bottom of the product is a silver end that accents the design and the trimmer is silver on the top as well, which houses the adjustable blades. Right at the center of the Panasonic ER-GB40-S is a circular power button of a lighter shade of blue, and above that is the bright silver dial. All in all, the product ensures an ergonomic design that looks very appealing.


er3Being an award-winning trimmer approved by Men’s Health in 2013, the Panasonic ER-GB40-S is sure to work efficiently and is a reliable product. The trimmer has super-sharp, stainless-steel blades that are installed at a 45-degree angle so that the cutting edge provides quick hair trimming and a brilliant performance. Its blades are fully adjustable too, and the dial allows the trimmer to quickly shift between 19 precision settings between 1-10mm so that you can trim, sculpt, detail and cut your hair just as you desire.

Adding to all these features that guarantee incredible performance, there’s also the feature that the trimmer works with both wet and dry conditions with an easy-open water drain, which allows the product to be cleaned quickly under running water in the sink. Lastly, the battery ensures up to 50 minutes of continuous usage after being fully charged and takes only an hour to charge on the charging stand. The trimmer itself is cordless, but it can also be used while connected to a power supply with no issues. The overall performance of the Panasonic ER-GB40-S proves that all of the awards and mentions that the product has gotten are all well-deserved.


  • Award-winning product
  • Wet/dry operation
  • Corded/cordless operation


  • A relatively short battery life, so corded operation is recommended
  • Trimming is a little rough with the guard off; many customers prefer keeping the guard on


The Panasonic ER-GB40-S is a very powerful trimmer with incredible ergonomics and satisfying performance both in dry and wet conditions. It’s highly recommended for use.
