I love my new bottles! They make getting enough water easy during a busy work day. I get compliments on my bottles. The koozies are pretty as well and protect the bottles from all the little bumps throughout the day. The drops make drinking water fun and refreshing! I want more bottles and flavors for my collection. The bottle brush makes cleaning my bottles very easy so I never have to play with plastic bottles again. The only thing I would change would be the koozie that comes with the snow bottle. It needs a long side strap like the others. Having one on the side makes carrying and drinking a larger bottle easier and more secure.
