Pros & Cons
Pros
Don't leak. Easy to clean when you don't let milk/formula dry up in the *. Works well and baby takes the bottle just fine.
Cons
Stick with kernston’s runner *. The batch we received are terrible. Very disappointed and a waste of money.
The seller needs to update their product imagery. The product in the description and photos is the old version. The price is ridiculous for the new ones that you can find in any store now for around $7.
