At the price of greeting cards, this is a must. The 2015 edition has many more designs than previous editions. Super easy to use. This will pay for itself in no time.

NOTE: THE MAT I RECEIVED DOES NOT HAVE RIDGES AS PICTURED. IT IS SIMPLY SQUISHY AND FLAT, WITH A THICKER EDGE. But this fact isn't a game changer, more a shame-on-you for the seller post. This mat is pretty fabulous. It is cheap, and even though it isn't personalized with a personal mantra or a beach photo, it is so comfortable! My mouse lives on the corner of my desk in a perpetual loop of being knocked to the floor. This mat is large and oblong enough to rest on the corner edge firmly. This way, I end up resting my wrist on the thick edge of the mat in the most comfortable fashion, with the foam molding to the corner. The slant on the cusion even helps it stay oriented to my screen. Occasionally in my marathon chrysilis, I lean in awkward positions; this mat is a perfect elbow cushion. Plus, it arrived on Black Friday when I purchased a bunch of new PC games, thus the commendable rating.
