Bests & Worsts Reviews from Amazon

I bought this product in November, 2020 based on the reviews thinking that it would help reduce the pain I have in my left shoulder due to a rotator cuff injury. Nothing torn, just inflamed and stretched. Well didn't provide any relief as some have said in their reviews. I basically have three issues with this product. First (as I mentioned) it didn't reduce the pain when I tried to sleep. I also tried it when I jog and it didn't help there either. Second, the strap that wraps around your chest works its way up the side of your torso in no time until its right underneath your armpit. I finally gave up and just placed it there and tightened up the strap to compensate for the shorter distance. Problem is, not only is it uncomfortable under the armpit, it also takes away from the ability to immobilize your shoulder. And, if you're not wearing a shirt underneath the strap it digs into your skin. Third, be sure you go to the manufacturer's website and read their "100% satisfaction warranty - no questions asked" policy before buying it. What they don't say on their ad (and can only be found on their website) is that it's only good 30-days from the date of purchase. That means you better try it on right away to give it enough time to see if it works for you before the 30 days are up. Top it off, if you're not a Prime member who would get it delivered the next day, and you chose regular shipping you could be looking at a 25 day trial period. Not that long when it could take twice that time to really see improvement in your shoulder injury.
