Diva cup?

⚡️LaLuna • My beautiful rainbow baby arrived on her due date! Baby girl born on 7/2/16. :)
So I've been hearing a lot of girls on here praising the diva cup. I'm kinda curious and am considering purchasing one. I was wondering if any of you ladies had a certain brand that you'd recommend or any other things I should consider before getting one. Seems like a kinda cool invention.  Thanks!  :)
