Query: I loved it at first.........

At first it was perfect, but after 6 months of very sparse use it's neck cracked and I took very good care of it. Then I got the whole thing replaced and 2 weeks later the new one was cracking too and on top of that it's suction totally ....! I had to start using my Medela hospital grade. Also the ice packs only stayed cold for 2 hours, which caused my milk to spoil! Other than the pump, all other Avent products are great! with the exception of minor leakage when it comes to the sippy cups.
