“I love that the cup is leak proof but the lid is sometimes difficult to untwist especially if you have arthritis or lower hand strength. I actually snapped the handle off the first Hydrojug I purchased.”
“Doesn’t leak as advertised! However, the lid did end up growing mold. It was my daughter’s fault, she used her hydro for her supplement water and didn’t wash it as often as she should. I have one and have only used water in it and so far it hasn’t molded. I’d say use these with just water.”
