Parent Units Sipping Spout

2nd revision: I need to write a revision in these sippy spouts. Once we started opening the cute variety of colors we ended up finding out very disappointingly that the ONLY colors that worked on the “suggested Dasani waters” were “Aqua, Red, Blue & Gray”, which were perfect! The pretty vibrant colors “Green, Yellow, Pink & Lavender” did NOT fit. A lot of work for something so cute NOT to work. 1st review: I bought these for my granddaughter's 1st birthday party to use with small water bottles. The reason I gave the "leak proof" 4-stars is because you MUST buy the recommended water, "Dasani or Aquafina" (which they do recommend on the package) for the sippy spouts to fit securely. Reminder though the sippy spouts are not spill proof. These are great for on the the go!! I put all of them in a dishwasher dispenser (top rack) (baby bottle cap & nipple dispenser works great) and bought very small zip lock bags and put each one in their own bag. Put them in a basket beside the small waters and Mom's & Dad's had easy access to waters with sippy spouts for the birthday party and were able to take home with them to use later.
