Two thumbs up!
I was stoked to purchase this item because my shoulder/right rotator cuff injury can be a painful experience like at times when I need to type.  I also sometimes just like to give my arm/shoulder a rest and this offered both- relief & support! One more thing, although it is easy to put on, the only downside is how it feels under your armpit when first put it on.  I got used to the feeling quickly but this might concern another person who buys it.
