We have all of these cups & have been using them for a while now so I feel like I can give my honest opinion on all of them. We began using straw cups when we started solids so that we could provide water while she ate. I also found that since she was using them so often we had ZERO issues when it came time at 12 months to completely drop bottles! This was one of our first straw cups Mackenzie used! We’ve only ever used it for water & it’s worked out great. I’ve never had any issues with it leaking and she can drop it without it…
