Review on Brita 32 Ounce Stainless Steel Water Filter Bottle in Carbon - Holiday Gift, 1 Count by Trevor Palmer

I bought 3 bottles in March 2020. At first I was able to wash and clean the Easy-Sip Straw, but now the black stain is permanent and there is a ring around the bottom opening that looks like mold. I stop using it. This is a dangerous product and an expensive bottle. The filter has been changed several times. I am very worried about my health. Don't buy it. Also, you won't be able to fill the bottle completely because the water will overflow as soon as you put the lid on it. I'm really disappointed and very embarrassed because the other two bottles were gifts. See photos please. I don't usually have time to write reviews but this is too much my health is in the middle.
