The Jokin Joes has been used, but I think it's fine since I was using it until last month. (I have the box, but I closed it once, so it will be assembled with tape, but please let me know if you want me to assemble it.) The Chubo was stored for emergencies, and I have all four. I'm also using Milk de Pon W, and I have 17 packets left, so I hope you can use them together. I'll include a GAP bib as a bonus, which I think I used 2 or 3 times! (Please comment beforehand if you don't want it) I think this is an essential set for bottle feeding, so please consider it!
