These items were used by my son when he was playing baseball. The ALGO water bottle has a crack in the handle attachment, but it doesn't leak and can still be used. The Captain Stag bottle was only used for iced tea duty, so I never put my mouth on it. Both were used for only 1-2 years during the summer. They were taken outside, so there are scratches on the bottom. They were washed afterwards and stored in a storage container for several years. I think the insides are relatively clean.
