Can't wait to try my new pillow.  My cousin has this one & I loved it. We already have the Balance 3.0. I always run HOT, arthritis in neck, toss n turn all night.  Hoping this pillow improves my sleeping game! Giving a 4 rating for now because I just got pillow & warranty set up has this part here. So far though, it's cool & comfy!! May be a 5 after I sleep on it.
