Panasonic ER-GB 40 Users’ Opinions

Most users agree the Panasonic ER-GB 40 is a very well-made hair trimmer, in spite of its low price. Quite a large number of users mentioned the fact that this trimmer has just as many features as more expensive mens shavers and costs a fraction of the price.

User reviews also mentioned that this shaver is ideal for men with sensitive skin. The trimmer guard keeps the blades far enough away from the face so as to avoid irritating the skin. However, the quality and closeness of the trim are not affected.

Some reviewers also highlighted the fact that this shaver is easy to clean and maintain. Overall, many users recommend buying this shaving device over others for its solid build, high-quality razor blades, and ease of use.
