Title: after a certain period the bottles leak around seals on bottom!!!
Review: I have found that after a certain period of time all of the bottles began to leak!!! Around the bottom!! The seal just was not efficient enough even changing the disc did not help...I had used them for about six months and then all the bottles began to leak... The only ones I have not had leak on me arethe red ones which have different discs!!!!!! My son like them but I did not!! Way to many parts and the parts all began to leak!!! That Sucks!!!!!!!
Is the review positive or negative?
