I really tried hard to love this item but I had to get three of these within a month. The first one leaked very badly in both the middle sitting area and the actual duck itself. I exchanged it as defective. Amazon sent me another. The second one had a slow leak for the duck but the sitting area was perfect without leak. I had to fill the duck with air 3 times within a week so that was pretty much defective too. I hoped 3rd time would be a charm. I tried to exchange again but Amazon only allows one exchange so instead I had to return and repurchase. The third one came in and its missing the "quack-er" in the nose which my son loved with the previous two. Its the same exact product so they simply forgot the quack-er.I'm very disappointed but I'm going to try this third one anyway to see if this one also leaks. If it does, I'm done with this brand for good. I'm surprised to see it get such high reviews overall, am I just that unlucky?
