[This review was collected as part of a promotion.] The moment I got it, I opened that box. I had neck and lower back pain. I put it on Saturday morning around 10am. I felt it heating up within five minutes. My pain was calm within twenty minutes. By the time one hour had passed my pain was gone. I went out and danced my life away that same night, and my pain did not come back. I had it on for over five hours. I am extremely happy with this product.

[This review was collected as part of a promotion.] I have chronic muscle pain so I was super excited to try this one. It stayed in place the entire time. And it actually helped dull my pain. I definitely recommend this product for anyone with neck/muscle pain.

[This review was collected as part of a promotion.] Packaging was nice comes as a 4pack, Intructions clear aand easy to follow. I applied it to my back neck area, heat was nice slow in progression. While i had it on. had to keep readjusting it to area, it kept moving. i kept it on for 3hrs no uncomfortability,thamk you for th opportunity to test;

[This review was collected as part of a promotion.] I found this product to be very accurate to the description on the outside label. I appreciated that there was more than one item to be able to test multiple times. The product heated up as stated and remained warm for the length stated on the packaging. My one complaint is the sticky parts don’t keep their sticking power very well if you have to re-position. Overall, I thought the product worked well and it helped my sore shoulder feel better.

[This review was collected as part of a promotion.] I work on a computer all day long and my neck is constantly stiff. I’ve tried creams and other contraptions but this stick on worked all day and you feel it immediately! I’m already looking to purchase more to keep on hand!

[This review was collected as part of a promotion.] I loved this product! It gave me just the right amount of heat I needed on my neck. The only thing I didn’t much like what the stickiness of the sides. I wish it stayed on longer but it kept moving. Overall not a bad product

[This review was collected as part of a promotion.] These wraps are nice for tired muscles. They are air activated, which is very unique and I have never heard of. Although they did not eliminate the pain they did provide a nice warming sensation to help sooth my achy body.

[This review was collected as part of a promotion.] I was skeptical about the whole 16 hours of deep penetrating relief. I wore the patch for 6 hours, because the adhesive did not hold. While the patch worked well, I began to hurt again after a few hours of taking the patch off. I like that there is no messy cream to apply and no smell. It's not just for your neck, it can be placed anywhere you have pain.

[This review was collected as part of a promotion.] I love this product! It is very effective in keeping my neck/shoulder pain mostly in-check. I have 3 bone spurs on my upper spine/neck that neurosurgeons want to remove. I'm not ready for that yet. So, for now, this product offers more pain relief than ANY OTHER pain relief patch out there, even R/X Lidocane patches! For me, this product works even better than the 8 Trigger Point Injections that I receive from my doctor. I would highly suggest this product to family and friends. A+ to infinity!

[This review was collected as part of a promotion.] I have neck issues and this works on helping with the pain. You put it on your neck and it then activates the heat. There is a small issue of some of it not sticking to skin, but instead sticks to your hair. Otherwise great product for neck pain.
