My toddler loves this cup! It doesn't spill and although it is difficult to open, once I figured it out (read the instructions), it was not difficult at all. The only issue is my toddler likes to bite the silicone straws; I had to cut it short to prevent her from completely biting it off (a choking hazard). But then the straw is too short to fully drink from it. The cost of the replacement straws (package comes with 2 straws) is about the same as buying two brand new cups. None of the stores carry these items where I live so online order is the only way I can get these and the replacement straws.

Avent Straw cup is in very solid quality! The price is expensive but it is worth for it! But I found that the straw is quite hard for a toddler to get the water out from the bottle, even I try also feel hard. Hope they will improve in this problem. If the price can be more premium than it will be more convenience for every parents!
