I picked up this Protein Shaker Lid to convert my Go Cup XL, and it does exactly what it promises. The built-in agitator mixes protein powders and greens without clumps, and the flip and sip top stays leakproof in my bag. I also like using it as a fruit strainer for infused water. It separates for easy cleaning and goes right in the dishwasher. Simple, practical addition if you already own the Go Cup XL.
