Easy to maneuver: Since much of pubic hair grooming involves navigating wrinkly, foldy, and extremely delicate flesh, we looked for models with smaller heads, which were generally easier to wield and small enough to move around bends in skin.Flexible with guard settings: Depending on the aesthetic you’re going for, having a few guard settings will give you more hair-length options, so we looked for models that offered a range of choices.Rechargeable: We looked for models with rechargeable batteries.Cordless: Being tied to an outlet limits where you can use a trimmer.(Water resistance isn’t waterproofing: Don’t expect your trimmer to survive a dunk in the tub.) Water resistant: Because these are tools some people will choose to use while they shower, we wanted to make sure they could indeed get wet.
