Query: Worst Sippy Cup Ever

In the effort to show our 23 month old daughter how to use a straw we figured this sippy cup would be great. We purchased it yesterday and she absolutely loved it! She enjoyed using the flip top for the straw and thoroughly enjoyed using it...until...she dropped it by accident and the bottom shattered into a gaping hole. We had the cup less than 24 hours and it was completely destroyed. THESE CUPS ARE NOT DURABLE AT ALL!!!
