Panasonic's latest is fairly devoid of accessories and features for its price tag (it's the most expensive on this list), but it's nearly perfect for a no-frills trimmer. With 19 length options (1mm to 10mm), the unique 45 degree angled blade achieved a close and even trim with every pass, and cleaned up with ease thanks to a waterproof construction that allows water to flush through the head.
