Wirecutter's top beard trimmer. It has enough power for most beards, 12 guides, a 5-7 hour battery and blades that never need oil. It is heavy for travel and may struggle with the thickest beards. Wirecutter's clipper testers found the previous model weaker than real clippers for haircuts.
Top complaints
- Not enough for the thickest beards or full haircuts
Wirecutter says it may struggle with the thickest beards and suggests the Wahl Aqua Blade instead. Wirecutter's hair-clipper testers found the earlier MG7750 less powerful than any of their clipper picks and a pain to switch guards on during a haircut.
- Heavy to pack, slow to charge
Wirecutter says it weighs nearly half a pound, which is noticeable in an overnight bag, and a full charge takes about five hours.
Source: Wirecutter (beard trimmers) - Mixed durability; no wall charger
Amazon's summary for the MG7975 says durability feedback is mixed, with some owners reporting it broke within two days. On the related MG7970 listing, some owners complain that no charger is included and call it overpriced.
What owners love
- Lots of genuinely useful attachments
Wirecutter lists trimmer heads in three widths, 12 guides from 0.5 to 16 mm, an effective nose and ear trimmer and a foil shaver head, all easy to swap. Amazon owners praise the variety of attachments.
- Very long battery
Wirecutter got five to seven hours per charge, and a five-minute charge gives a couple of minutes of trimming. Amazon owners say a charge lasts a couple of weeks.
- Low maintenance, solid body
Wirecutter says the self-sharpening blades need no oiling (one tester used a Norelco for six years without sharpening), and the grooved stainless steel body grips well and stands upright.
