The Written Review

After lots of research on the reviews for this product, we’ve come to some conclusions that may help you in your decision to buy a facial hair trimmer.

With this Panasonic ER-GB40-S being a wet/dry trimmer, it is a pretty good option to use in the shower for a quick trim. Not all trimmers give you this option. This model is actually built to be run under water, as it has some water holes to let water run throughout it and clean it out well.

The stainless steel blades are going to help ensure that you don’t get any annoying and painful snags while shaving, and also help reduce the risk of razor burn. You’ll be able to get the perfect trim and precision to your beard or goatee with this all-in-one model.

This unit it rechargeable, and will last up to 50 minutes on a 15 hour charge. This seems like a lot of time to charge before use, but as long as you put it back in the charging holder it comes with, you should be fine. The light on the stand will glow red which charging so you know when there is still some time left. The unit itself actually has a light that glows red when the battery is low as well, so you can be sure to put it back in the stand before it dies on you half way through a shave.
