If you’re looking for the effect of icy hot this is the best product to buy. I have always hated applying icy hot because sometimes you don’t have access to a sink to wash your hands after (like at practice or the gym) and ultimately your hands get the icy hot effect as well. Typically i prefer to use the extra strength for sore muscles because I feel more of a penetration and relief when exercising as oppose to the normal strength. I have used this on my hamstrings, thighs, lower back, etc. Being a division 1 athlete for 4 years icy hot becomes a best friend after Long practices and training days. The roller ball provides no mess in your bag when storing and leaves no residue on your hands after application. Thus, no need to worry about not touching your face or rubbing your eyes. When you’re at the gym or working out worrying about extra things is the last thing you want to think about. This applicator allows you to just simply focus on your exercise while provide relief.
