I absolutely love this sterilizer!!! I wish I had one when my older 3 children were babies. In the past I used a microwave sterilizer with limited space so I had to sterilize all the bottles and pump parts in small batches and it was very tedious and time consuming to have to dry each piece afterwards and assemble everything. With this sterilizer I can just throw everything in, add 100ml of distilled water to the hot plate, and start it, which is simply turning the dial all the way to the right (no complicated buttons or settings). It takes a little over an hour for a full cycle. There is also an option to just dry so you can throw everything in and just turn the dial and stop it at the little dryer icon. I have 3 different breast pumps and quite a few baby bottles so I use this product twice per day in the evenings, one cycle to sterilize all the bottles and bottle pieces, and then after my last pump of the night I put all my pump parts in the sterilizer and start it so in the mornings I just have to quickly assemble the pump parts and have them ready to go. I recommend the larger size sterilizer if you have a lot of pump parts and bottles like me. However, it is quite tall and wide so keep that in mind if you have limited counter space. I did have some rust and lime scale build up on the hot plate a few times (probably due to tap water splashing in while transferring the washed bottles from the sink to the sterilizer), this issue was easily fixed by adding 80ml of white vinegar and 20ml of distilled water to the hot plate and letting it sit for 20 minutes. Then the rust and lime scale was easily removed with a tiny brush. Then I wiped everything down with a cloth and it was as good as new again. I cannot stress how much I love this product and I would highly recommend it to all busy parents who want a quick and easy way to keep their baby bottles and breast pump parts clean and sanitized on a daily basis.
