Query: Read the instructions!!

Looks like i am not the only one who loves this pump. It also looks like i am not the only one who didn't read the instructions that well regarding the neck of the pump...you know, the bold faced text that reads "DO NOT OVER TIGHTEN". But seeing how many others did the same thing i feel a bit less stupid now. I will just be glad to get my free replacement part (you have to love customer service like that!) so i can start using it again. I am currently using a little Ameda pump to get by with and i miss my Isis!I highly recommend this pump to anyone who can remember not to over tighten the neck...
