Review on Neoprene Iced Coffee Sleeve - Insulator Sleeve for Cold Beverages, Neoprene Cup Holder - Compatible with Starbucks & McDonald's Coffee - Medium Midnight Mums - Koverz by Amy Fuhrman

I have two things that I love very much. My first one still looks brand new after 1 year of regular use (about 3+ days a week). The colors in real life are just as beautiful and vibrant. The base always lies flat and sits properly on flat surfaces with ease. They absorb condensation indoors well, but I'll say the more the drink sweats, the wetter the sleeve gets, which is understandable. So be careful, bring it outside and then plant it on your wooden/nice furniture. Otherwise I have no complaints! For reference, my sleeve size M fits medium-sized McDonalds, Wendy's drinks; Sleeve size L fits most large drinks I've tried. I haven't really tried it on monster sized drinks (which are smaller at the bottom) because I never get it, but once I tried it molded around the cup like a glove. Haven't tried the competitor Java either, but for my needs these cases are great for me.
