I have been using the avent glass bottles for my son. But after his first birthday we wanted to win him from the bottle to a sippy cup. I was very escrows to try this cup! I love that it comes with both the nipple and sippy spout. I haven't seen another bottle come with both. The sippy spouts dentally have to purchased separately. Also this bottle came with the handles and a silicone bumper, both of which generally have to be purchased separate. The bottle is a very high quality material and quite durable. The sippy spout and nipple also are very durable! Nice thick silicone that you won't rip just by washing! All in all I do recommend! Also the borosilicate glass is durable but lightweight. This is much lighter than my avent bottles were!
