I have been using this sterilizer for about 3 weeks now and I use it about 3x a day. I wanted to give a honest review for anyone who is looking for the pros and cons of this sterilizer. I am going to first start off by saying this is for the standard sterilizer, not the Pro version. With that being said let’s get into the things I liked.PROS- definitely saves time opposed to boiling or using bag sterilizers.- it is very quiet and even standing next to it you barely hear it- it dries completely on either the 45 or 65 minute cycle (options shown in photo). Either cycle has proven to dry without leaving very many of any water spots on items.- it is easy to use- it fits under the cabinets if your looking to store it out of the way.Now for the cons.CONS- the most annoying thing I deal with is oil/grease residue. I exclusively pump, so my breast milk forms fat layers in the bottles. Even if I wash them with a brand new brush, an over abundance of dawn dish soap, scalding hot water, and hand dry them, there seems to still be a 50/50 chance those bottles which STORED my milk comes out with grease/oil residue on it. The regular bottles I use for feeding and everything else comes out perfectly clean. I am not sure what is causing this. I don’t have this issue with bag sterilizers.- this version (the standard) is smaller than expected. I am able to cram my bottles and pump parts in but honestly the PRO version would be best if you use a lot of parts. It would be worth the extra money to have the extra space in my opinion. You can see in the photos I have attached what it looks like fully loaded with my bottle and pump parts.- doctor brown bottles are too tall to fit if you sit them on the spots made for the bottles. However, if you sit them just below that, then you are able to fit them in and close the lid. This is better explained in the photos I have attached.IMPORTANT NOTE- RUST ISSUE When reviewing this product for myself I seen A LOT of reviews saying that they dealt with rust forming in the first few days or weeks of use. I personally have not had this issue yet. I have had a tiny itty bitty piece of rust that formed and I literally scrapped it off with my nail and it hasn't came back yet. I use only distilled water in the sterilizer. I think one big mistake that people are doing who are using distilled water and are still running into a rust issue is not shaking off their bottles before putting them straight in the sterilizer. The purpose of distilled water is to keep minerals from the tap water from causing rust. But if your not shaking off excess water from washing parts in the sink before putting them in the sterilizer and that tap water drips down onto the hot plate, then your just adding mineral water to the distilled water and it is counterproductive. I have always been mindful of this and have shook off excess water before placing parts inside the sterilizer and I have never had a rust issue. The directions also state that rust or lime scale buildup is possible and what to do to avoid it (shown in photos). I feel like people do not read the full instructions and are shocked when rust forms and thinks the product is faulty.Overall I give this a 4/5 stars. It is great for the price and if you’re going to be washing your bottle/pump parts regularly then it is perfect. However, if you let your parts pile up before you wash them you definitely need to invest in the PRO version for the additional space. I hope my review answers questions you may have had. I really wanted to make a honest review and took a lot of time taking notes as I have used this sterilizer.
