The 4-ounce bottle sells for about $19, and the 8-ounce bottle sells for about $22. The nipples come in 3 flow rates for different ages. A 2-pack of nipples costs about $5. Although they are bit pricy, you definitely get what you pay for here and you will find that these are worth the few extra bucks.
Function, convenience and quality are the three best words that come to mind when describing the Mixie Bottle. It is a bottle not quite like any of the the others we have tried, with a a built-in formula compartment on the bottom allowing parents to preload the formula and then add water to the upper part. When baby is ready to eat simply push on the bottom of the bottle to open the formula compartment and shake to mix it up. The formula stays dry until feeding time, and you don’t have to carry a separate container to mix with your bottles (and the bottle is just about the same size as most other bottles and fits perfectly into the diaper pocket on most diaper bags and in bottle warmers).
The Mixie bottle comes in 4-ounce and 8-ounce sizes (the smaller bottle holds up to 2 scoops of formula and the larger bottle holds up to 4 scoops of formula). Another bonus, the bottles are dishwasher safe and are made of plastic free of BPA, phthalates and PVC.
