I tried them all!! Dr Brown's are simply the best and work so well in eliminating or reducing gas. My son hated Playtex ventaire and I was not happy with Avent. I intended to breastfeed exclusively but my son wasn't cooperative so I pump and supplement with formula.I have no problems cleaning them and I don't even have a dishwasher! I also had trouble with leaking when mixing powdered formula but the newborn set with the 8 oz bottles includes two travel caps that screw on and keep the bottles from leaking when shaking to mix.I can not say enough about these bottles. They are all I use and am so pleased!!
