How long should a beard trimmer last?

Verified-purchase reviewers on Best Buy and longtime posters on r/BuyItForLife regularly report 5–10 years of life from Philips Norelco and Braun trimmers used weekly, provided the battery isn't abused and blades are kept clean. Reddit threads also flag that within the same Philips series number, sub-models can differ significantly in build quality, so check the exact model code before buying.
