The size and shape fit well enough, but compare to other similar handles it’s just harder for my baby to uses. We have stoped using and and moved on to another product.
These handles are such a game changer! My little is 5m and has started grabbing the handles and holding his bottle!

Teether Handle for GentleBottle
Our bottle's nipple hole is not large enough for water to pass through. We have all tried multiple ways of getting water out and it is extremely difficult. Furthermore, any kind of sucking or squeezing of the bottle only creates huge indentations in the bottle as weird air pressure issues inside the bottle begin to cause the lid to leak out of the side of the bottle. Needless to say, this has not been a good purchase and we've already put it in the cupboard likely never to be used again. A real bummer.
