Bests & Worsts Reviews from Amazon

I bought this water bottle for my trip abroad so that I wouldn't have to buy so many disposable plastic ones. I would wash the mouth of it everyday and the bottle as a whole every three days. I left it for a week while I went on another trip and I came back to have it full of mold. After that, I was never able to get it out. It was in the cap under the rubber part where I couldn't get to it. It was in the bottom of the bottle where I couldn't reach. I'd try to soak it in hot soapy water to loosen it and hopefully get it out. The mold in the bottom would seem like it was gone but the next day when I was drinking from it, it'd be back again. I quickly threw this out so that I wouldn't get sick from it.
