Playtex Ventaire Advanced Wide Baby Bottle Review

I GOT TO TRY THESE BOTTLES FOR A PRODUCT STUDY. I HAVE ALWAYS USED THE REGULAR PLAYTEX DROPINS AND HAVE LOVED THEM. SO I WAS EXCITED TO GET TO TRY THESE. THEY REALLY DO EASE THE GAS AND SPIT UP BUT YOU HAVE TO BE VERY CAREFUL OF THE PLASTIC PIECE IN THE BOTTOM OF THE BOTTLE IF IT IS NOT COMPLETELY DRY OR EVEN GETS SLIGHTLY NICKED IT LEAKS LIKE CRAZY. I GOT THE STARTER PACK OF 3 BOTTLES AND MADE SURE TO WASH THEM VERY CAREFULLY. BUT WITH IN A WEEK ONE OF THE PLASTIC PIECES THAT GOES IN THE BOTTOM OF THE BOTTLE HAD GOTTEN DAMAGED AND I HAVE NO IDEA HOW. THE PLASTIC IS SO THIN ON THE PART THE COVERS THE HOLES. OF COURSE I DIDN'T REALIZE IT WAS LEAKING UNTIL I WENT TO PULL THE BOTTLE OUT OF THE FRIDGE DOOR AND IT WAS EMPTY AND THE WHOLE SHELF WAS FILLED WITH FORMULA LOL. JUST BE VERY CAREFUL!!
