One of the two best-selling warmers on Amazon and the fastest water bath in expert tests. Both Wirecutter and BabyGearLab found it can overheat milk, especially if the bottle sits in keep-warm, so it suits people who will stay nearby.
Top complaints
- Overheats, especially in keep-warm
Wirecutter says it tended to overheat glass bottles and its auto-shutoff only kicks in after one hour. BabyGearLab saw contents pass 104°F near 7 minutes (max 121.6°F following instructions). Amazon's summary says some owners report it overheats milk.
- Inconsistent temperatures
BabyGearLab measured a 22°F spread at auto-shutoff. Babylist cites reports of inconsistent temperatures, and Amazon's summary calls warming performance mixed.
- Hard to clean; no bottle basket
BabyGearLab says spilled milk can reach a heating element you can't clean, the manual's cleaning guidance is only icons, and there's no basket to lift bottles out of hot water. Babylist calls cleaning around the element tricky.
What owners love
- Fastest in BabyGearLab's test
80°F in 4.5 minutes and 98°F in 6.5 minutes; Babylist names it the fastest pick.
- Simple one-dial control
A press-and-turn dial set by ounces, easy to add time (BabyGearLab); Wirecutter liked its streamlined interface.
- Popular and well rated
Over 15,000 Amazon ratings with only 7% at 1-2 stars; Amazon's summary says customers find it a good purchase.
- You might walk away mid-cycle
- You use very wide bottles
- You want easy cleaning
- Speed
- A one-dial interface
- Glass bottles (per Babylist)

What experts say
- BabyGearLab: Ranked 8 of 11: well designed and the fastest tested, but it can overheat on keep-warm (health and safety 3.0/10), so only for users who will watch it.
- Wirecutter (NYT): Not recommended: streamlined, but it tended to overheat glass bottles and only shuts off after an hour.
- Babylist: Fastest: can warm milk in as little as three minutes and works with glass, but efficiency reviews are mixed and wide bottles may not fit well.
