I love his cup! It holds a lot l, is still portable, is sturdy, and has a great price point. I usually clip the loop to my backpack when hiking so I need something very durable, and this one holds up with no cracks. As long as I continue to make these I will continue to buy them!This is a great mixer. It's short and wide which mixes quickly and the container doesn't tip over easily. The only problem is opening the spout. Had to build a special tool to get it open.. At least it doesn't leak.No leaks! The lid flips closed while you are pouring, otherwise this product is a good value and quality.The item worked as it should was just what I was looking forI had a shaker, years ago, a Tupperware one. I was worried this one might not work as well, but it did.The lid is a little rough. But it’s good for the price.It’s a starter shaker bottle. Perfect for mixing your protein and creatine and whatever substances you add.Basic shaker bottle, no complaints
