This is the second rain cover we got for our Britax Vigour 4. The first one was terrible, unfoldable, occupying the whole of the basket when not in use, making the basket unusable for anything else, really hard plastic which my child hated, and which ended up cracking and cutting my finger! And truly difficult to place on the chair - awful stuff, in fact! This one is so much better, made of soft plastic, very easy to put on and store, folded flat, in the basket. The only thing is the instructions received are wrong, but the cover being so easy to put on, that's such a small detail. Still, the instructions should be correct!
