The Panasonic ER-GB37 sits at number four in this guide at £23.99, and it is the cheapest trimmer on the list. It is also the only one whose listing states a standard 3-pin plug in the box: the Braun Series 5, 7 and 9 entries above it all list a 2-pin charger, which means an adapter for a normal socket that is not included. On the cutting numbers, Panasonic lists 20 lengths between 0.5 mm and 10 mm on a turn dial — more settings than the £49.29 Philips 3000 Series trimmer further down the list, which is listed with 10 over the same range for more money.

The rest of the listing is less tidy. The 40 minutes of usage appears in the product title only: nothing in the specification table says how the trimmer is charged, and the table separately answers yes to "Are Batteries Required". The special features field reads "gentle and precise epilation", which is not what a beard trimmer does, and the specific-uses field still shows the placeholder "[POSSIBLE VALUES]". What is consistent: 20 lengths and 0.5–10 mm in the bullets, and "Maximum Cutting Length: 10 Millimetres" in the specs. The 4.4 rating comes from 2,079 ratings, with the breakdown weighted to five stars — 64 five-star marks against 4 at one star, and the trimmer ranks 21st in Facial Trimmers. Everything on this page is taken from the Amazon listing, not from our own testing.
