Bests & Worsts Reviews from Amazon

BEWARE! After few days of usage - the mold start accumulating in the top of the cup. Then longer you use - then more mold inside,which is impossible to reach. As many times i cleaned it - doesn't help. Today found the way to clean the mold. I just start to add water 1/3 of the cup,closed it and shake well. This case mold goes outside in the water and you will be shocked how many mold is there. I repeat that 10 times and mold goes to the water again and again and again. So i just gave up and decide do not use these cups anymore. I feel guilty,because i know now that my child swallow this mold so many months with juice and tea i gave him and i really worry that it will not affect his health in a future.SO BE AWARE and do not use these cups. P.S. ACTUALLY I FOUND ONE NEW MODEL - "CONTIGO STRIKER CUPS" THAT IS SAFE AND LEAK PROOF. IT ALSO HAS THE SCREWS IF YOU NEED TO OPEN AND CLEAN TOP FROM THE MOLD.HERE IS THE LINK THAT I DO RECOMMEND TO BUY INSTEAD OF THIS CUPS. STILL NOT SO HIGH REVIEWS,BUT IF COMPARE TO THESE CUPS - CONTIGO STRIKER CUPS MUCH BETTER,AT LEAST I DONT HAVE ANYMORE ISSUES WITH MOLD. http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=contigo+STRIKER+water+bottle&rh=i%3Aaps%2Ck%3Acontigo+STRIKER+water+bottle
