|My photo from selling my replacement Flip trainer|
Ugh, what a saga with the Flip trainers. Long story short, I would never recommend these because they are poorly made (a snap broke off after about 3 uses), and are really difficult and annoying to use! The velcro on the shell/pad was incredibly finicky to put in, and they made it so you can't use other pads in it (easily). I've sort of put this out of my mind because I had such terrible customer service from Cottonbabies. I do love their BumGenius diapers, but I kind of hate them over the shoddy Flip and my awful experience. :(
Don't buy the Flip trainer.
