Only ever used a couple times, I have 2 filter pieces that come with it which makes it more convenient! It’s a little dusty from just sitting for months but I’ll clean & empty it before purchase! I purchased this for 300$ & the cheapest that you’ll find this for is around 270$ - 300$+ it connects to your phone so you can make a bottle without having to touch it! We loved it! My baby just wasn’t on formula for very long so we no longer have use for it.
