When they arrived, I was excited that mine was purple, my favourite colour. The kids' bottles come in three fun designs and are a smaller version (384mL) of the adult model, but with slightly softer sides. All in all, we really like the Brita bottles. My only complaint would be the sports top, I just am not a fan, but I understand with this bottle and how the filter works, it's probably a necessity. Up until when we got these, we were packing at least 3 large bottles filled with water before we headed out anywhere. Now that all we need is a tap, we only have to take these two... and not have to ration the water. The filters work excellent and take all of the 'tap' taste out of the tap water, and the bottles are easy to both assemble and wash (all can be washed except the filter, either by hand or on the top rack of the dishwasher).
The kids bottles are definitely easier for the li'l ones to hold on to, but Chelsea and her friends happily use either! The Brita Kids' Bottles are now available at mass merchandise stores across Canada and have a MRSP of $8.99 (and a two-pack of the replacement filters MRSPs at $7.99... you only have to replace them every 2 months or 151 litres). Of course, the Brita bottles are all BPA-free and recyclable.
