With 175 different length options (from 0.4mm up to 18mm, in 0.1mm increments), this LED-touchscreen trimmer offers the most versatility of the bunch. It's a shame, then, that its screen is too sensitive – if you leave it unlocked, one tap can cause its length and speed to jump several levels. [$55; remingtonproducts.com]
