Query: but have been very happy with the other two

Bought this set mainly for the medium sized filer to keep in my bag, but have been very happy with the other two. The smaller one i use on my 3 month old, and the larger I keep at my desk at work. But after only a few weeks the medium one cracked...not to any defect of the product I don't think, but buyer beware...crystal isn't strong enough to survive life in a busy woman's bag!
