I was a little concerned it wouldn't fit after reading many reviews. But there aren't that many covers for the back of 311, so I decided to take a chance. This case is very beautiful. The plastic dispenser doesn't feel cheap and snaps straight into place without having to wrestle with it. The lids were also easy to remove when I wanted to take them off (the clips are a good thickness so they don't break easily). So I have attached lots of photos and videos to make it easier for people to buy this for their Spin 311.
