I do really like this bottle but the coating on the inside is already wearing. I only ever used it for water or swash. At first glance I thought the bottle had gone mouldy but after a closer look you can see it's clearly the coating coming off on the inside. Other than I love the bottle but can no longer use.

I've wanted one for a long time, it was a great price with discount, it does the job very well, no leaking, I carry it two miles to work so easy to hold, keeps that water cold too.
