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.These are nice shaker cups for small protein shakes, but sadly, they crack very easily. We have clumsy kids and two of these cups have cracked when they’ve dropped while full of liquid. Great cups, but only if you’re not accident prone. ?Great shaker for mixing the stainless steel ball inside is great mixes everything really good
