The ThermaCare Neck and Arm HeatWraps are a great quick fix when you're in pain and need an inexpensive disposable heating pad. The great thing about the pad is that the adhesive really sticks so you do not have to worry about it moving from where you place it, especially since the neck and arm can be a tricky spot, location wise. The best thing, however, is how well the heat from the wraps last so long! I do not know how ThermaCare does it, but the heat lasts for hours! Effectiveness Overall, the ThermaCare heating pads work pretty well. Obviously, you wouldn't make them your normal routine. However, they definitely get the job done. I do a lot of heavy lifting my job so my arms and shoulders really suffer for it. I keep a wrap in my car for the ride home and the heat lasts me the entire night! Ease of Use These wraps are extremely easy to use! The box has step by step instructions with pictures to help illustrate how to apply the wrap. I think anyone could use this wrap with little to no problems at all!
