SUPRENT Wave Glider 5-in-1 Beard Trimmer vs SUPRENT GK215BX 16-Piece Grooming Kit

Both are SUPRENT grooming kits with IPX7 bodies and USB-C charging, so the real split is runtime and heads. The Wave Glider BT576BX runs up to 3.5 hours per charge, has 40 length settings in 0.5mm steps and five heads, which suits anyone trimming beards, body and hair on one charge. The GK215BX spins a faster 7000+ RPM motor and packs a 16-piece kit with six heads, but its 1.5-hour runtime and coarser 3–12mm combs make it the pick for short, frequent trims. Owners of both report solid value for the money; the Wave Glider's ceramic blades and finer steps are the more refined cut.

• Choose the SUPRENT Wave Glider if you want long runtime, fine 0.5mm length steps and a head for body and hair as well as beard.
• Choose the SUPRENT GK215BX if you want a faster motor and the fullest accessory kit for short beard and hair trims.
