This is the best kit I've ever used! I started off with the plastic container (yes, I know this is bad to use plastic!!) then a stainless steel kit with a hose that had no one-way valve (shocked face!!!) and then finally found Happy Bum Co. I love that it is silcone and has a one way flow valve, so nothing can go back up the tube! Its easy to clean, easy to use and I love the Happy Bum Community! 10/10 hands down.
