First of all the size is fantastic. It easily covers my back, which is why I purchased it to begin with. It heats up quickly with a variety of heat settings, which is also wonderful. The auto-off feature is particularly nice because it will turn off by itself should I fall asleep while using it. However, I also have the option of overriding the auto-off feature, which most heating pads of any size do not offer. The controls are easy to read and easy to use. I love that the heating pad is quilted instead of having a detachable cover. The detachable covers always get twisted around during use. The instruction manual says you can use the pad for moist heat therapy, but I have not used it in that way, so I can not comment on it. The warranty is for five years which is far longer than the one year warranty offered by most other heating pads. The electrical cord is long enough that I don't need to use an extension cord. I've only had the heating pad for a couple of weeks, but so far it is almost perfect! The one and only complaint is that the connection between the heating pad and the electrical cord is a little big, but as the pad is very large, I don't really notice it. I highly recommend this heating pad!
