I use and am very happy with the Dr Brown's sterilizer. I typically remove the large section because it is fairly big and just use the tray. However, once a week I include the Aerobika so then I pull out the large section and use it. https://www.walmart.com/ip/Dr-Brown-s-Deluxe-Electric-Sterilizer-for-Baby-Bottles-Nipples-Other-Baby-Essentials-BPA-Free/797872985
