[This review was collected as part of a promotion.] My job consist of pacing back and forth all day while walking on concrete. After 2 to 4 hours in my lower back starts hurting. I like how easy this was to apply to myself and that it actually stayed in place. I put this on early afternoon and took it off when I got home late in the night. Just over nine hours and it didn't irritate my skin at all and just when I thought the cooling sensation was gone it would kick back in again. No problem with the corners sticking to my clothes or the patch starting to peel off. It really works and helped tremendously with the pain in my back. I applied the next day when I was off and slept through the night with it on and when I took it off I could still see the product on the patch. These lived up to the eight hours and I have already told the girls at work about this. The pack of five is perfect and will get me through the week at work and I absolutely recommend this pain patch. It's a ten out of ten for me!!!!

[This review was collected as part of a promotion.] These pain relief pads are very useful and work great. It smells a lot like menthol when you first put it on, but the smell goes away. It lasts pretty long and works well. The packs are helpful for traveling and are easy enough to throw in my bag. They’re pretty big and can cover anything I need them to. Overall great product.
