Buy the Baby Brezza Baby Bottle Washer Pro.

One of these actually cleans bottles. The other just sterilizes what you already scrubbed.

What was compared

1. It washes, the Avent only kills germs
The Brezza's 20 spray jets scrub milk and formula off bottles, independently lab tested at 0% residue after one wash. The Avent has no wash function at all, it just sterilizes bottles you already hand washed, so the actual scrubbing chore never disappears.
2. Bottles come out dry, not dripping
The Brezza's cycle finishes with an actual dry, so bottles go straight in the fridge or diaper bag. Owners who switched note the Avent will not dry bottles, leaving you to air dry them on a rack exactly like before.
3. One load does your whole day, not half
The Brezza fits 8 bottles plus pump parts in a single cycle. The Avent's basket holds 4, so a heavy pumping and feeding household is running it twice as often just to keep up.
4. Built to run twice a day for months
Real owners report running the Brezza 2-3 times daily for the better part of a year without issue, it is built as an appliance for that load. The Avent is a microwave insert meant for occasional sterilizing, not constant daily cycling.
5. Yes, it costs 10x more. Buy it anyway.
The Brezza runs $299.99 against the Avent's $26.76, a real gap. But if you are washing and sterilizing bottles daily for months, that buys back hours of scrubbing. If you are mostly breastfeeding and sterilizing occasionally, the cheap Avent genuinely covers you and we would not spend the extra money.
