So I bought first one a few weeks ago and the weirdest thing happened. The screw cap part where you fill the water just crumbled to pieces and broke off. I only used for about a week consistently and I already have to replace it. I got a second one only cause she needs one for now but it seems like this is a known issue with the product. Also it smells like old stale water after about a weeks use. Idk how else to clean it out. Ive cleaned it multiple times and smell wont go away.
