Okay, so I've been drinking Kencko drinks for a while and they require you to shake them up and sometimes they're still hella clumpy. Yesterday, I figured I kind of know how much of what I need now and don't have to have their little measurement bottle anymore and dumped it all in this Warroad bottle instead. Shook it up for far less time than I would have had to with the Kencko one and guess what? It was super smooth, no clumps. I've been living in clump land when I didn't have to! This bottle is AWESOME. Definitely ordering another one.
