Since my daughter had problems with bloating, and I had read in many forums of this bottle, I wanted to try it. I found the bottle not so hot: the first sucks the cleaning of many individual parts. You have to proceed very carefully when assembling, since the bottles are not properly sealed and otherwise expire. All I would have taken less bloating in purchasing. But our daughter could not cope with the cleaner form and therefore has the sucker often released and thereby again swallowed a lot of air. So for us it was nothing but an attempt is certainly worthwhile.
