Hi I am a first time mother and I purchased all of my feeding equipment from tommee tippee I have two complaints The first one is the electric steam steriliser I clean and descale it all the time but since the first use the ring inside it looks burnt and also has an awful smell It has also completely destroyed my kitchen the wall tiles, walls, sockets etc I have asked other mothers who have said they also have had the exact same problem I would change to another brand only I just recently replaced all her bottles to the anti colic tommee tippee and all teeth's too My second complaint is the anti colic bottles are absolutely awful the leak all the time I have spent a fortune on your brand and I'm extremely unsatisfied.
