The Wahl Cordless Magic Clip is a serious beard and hair cutting machine. With a variable taper blade and eight included blade guards, it's easy to fine-tune the look of your beard and hair. Designed with professional barbers in mind, this trimmer is built to last. The ergonomics of the handle are well-designed and comfortable to hold onto. One of the most remarkable functions of this device is its ability to be used corded or cordless. The ability to plug it in and keep cutting will keep you from ending up with a half-done job waiting for your trimmer to charge. At the same time, the rechargeable battery makes it easy to trim the back of your head without getting tangled in a cord or to take the whole operation outside. 
Using this device for small details might prove to be more challenging for less experienced users because it doesn't come with any blade guards that reduce the width of the blades. While this device is amazing at trimming and maintaining beards and haircuts, it's not ideal for removing small amounts of body hair and doesn't have any attachments to trim nose or ear hair. It's best suited for those serious about home grooming who want to skip going to the barbershop.
