I've had this heating pad for about 2.5 years and you will never know it by looking at it. It looks exactly the way it was when I got it, except for alittle wear to the fabric. It is extremely durable, heats quickly, and will stay heated for you warm-ups for a long period of time. One heat up in the microwave and mine stays warm almost until I'm done with my workout. It is very large too so it will pic any penis inside it's pouch. It has a slight smell, but it isn't a bad smell, sort of an herby smell. This product is worth the money. Perferct for the stealth Penis Enlargementer. If someone asks what your warming up just tell them a heating pad for your knee or elbow.
