I like this product for three reasons.
Easy to carry, Easy to Use and Easy to store for long time.

It is hard to use this product when the baby not eating 4 or 8 oz at a time since this is how they are pre-measured. But I think it is still a great product and very good for travel, daycare or at home. Enfamil is also great formula compared to other brands.

Note: You can easily split one package in half to make a 6 oz bottle. You can pinch the tube with your fingers and only pour half the package into the bottle.

Ordered with two day shipping and arrived as scheduled!!

This is a very convenient product. However, the only reason why I give it 4 stars is because you can only mix in 4 or 8 oz increments. My child is currently drinking 6oz.
