nothing to say, the handles are flexible and can easily catch the baby, it is very tough because already fallen several times without problem. the volume is sufficient for the water bottle of the day. nipple 3 does not interfere, boy 7 months without drinking problem. everything is easy to clean, good teat changes fast color if the bottle is used as me for water during meals, so she quickly tint with food, but it's for all such cups ... I bought the soft spout to fit on this evolutionary bottle, it attaches well, my son has trouble drinking with still no explanation .. by cons when mounting the spout !!! His brother the Advent learning cup with soft spout which is great, but impossible to find. this one will do if his twin figure out the flexible spout system.
