First of all, well.ca has excellent customer service. I emailed them after I ordered this to request that I not be sent a pink cup because the colors are sent randomly. They replied right away to say they added a note to my order, and sure enough I got blue and turquoise cups.
Unfortunately I don't like the cups. The spout is too far in the centre so my son has to tip it really far back to get the water out. And when he throws the cup on the floor, the whole lid pops off, spilling water or milk everywhere. This happened several times even though the lid was properly tightened.
