I'm not sure if I'm reviewing "Healthy Human" or the water bottle lids I purchased. Love the bottles and love the lids even more, except for one flaw. I use the "Flip and Sip Lid" which is almost perfect. It's the only lid I've found that has both a handle (so you can use a carabiner to clip it to something), as well as a locking mechanism so it doesn't spill. Only problem is they're a bit fragile. I've broken 3 of them and my gf has broken 1. It's the clear plastic bit. Sometimes they break in a way you can still use it for a while, sometimes its just toast. But at least they were on sale so I ordered 6 more. They're super functional but I really dislike how easily they break.
