These are pretty great quality shaker bottles. I’ve had two or three of these lids crack but I think that was because I tightened them too much. I have dropped these bottles on the pavement more times than I can count and none of them have cracked from it. They wash well in the dishwasher. They come in a variety of sizes, styles, and colors. I like to switch up the lids with different color cups. Great for all of my protein shakes, bcaas, and glutamine. I also use one on a regular basis for plain old water. I highly recommend these!
