BlenderBottle Strada SpongeBob SquarePants Shaker Bottle, 28 oz, Tritan Plastic, Leakproof Flip Cap, Wire Whisk Ball, BPA-Free, Yellow, “My Name’s Not Rick” Design

I love this! I read the reviews and they were mixed reviews, and I was skeptical. I needed a blender bottle, so I decided I would try it and if it didn't work I would just return it. Well I'm keeping mine! I haven't seen 1 review about the locking system at the top where you sip from. People are complaining about it leaking, but maybe haven't realized that you can lock it… and it says it in the instructions to lock it, just incase. It dosnt leak for me, I lock mine up when I shake it and when im not using it, I love how pretty the colors look! I guess the whisk ball works good, I'm using a new protien powder so regardless I have to let it sit in ice for a few minutes so it taste good, but I do use a frother to get that extra smooth creamy taste. I'm also wondering if someone just got a bad cup, because I love mine and love how you can lock it!!!
