I usually get a mix of 10-15 different brands and flavors to try new stuff, and most of the time it's great. Sometimes, I find a few I don't like, but that's just how it goes. This time, though, one of them was completely dead on arrival. It just didn't work at all. I'm hoping I can get a replacement, but I'm not holding my breath. I doubt anyone from the company will see this and reach out, but figured I'd mention it anyway. Thanks for the otherwise good experience!
