Simple and effective
This bottle warmer works on both bottles as well as frozen breast milk bags. It’s a simple one piece design so nothing complicated to use or clean, and it works quickly and cleanly.

Night-time ease
This has made night-time feedings so much easier! It fits on my nightstand so we don't have to go up and down the stairs in the night.I just wish it held more water to cover the bags better, but it doesn't impact its function.

Bottle Warmer
I bought this for my sister for my niece. It stopped working after 4 months. When we put the bottle in, it will make sounds but won’t warm up. I will definitely not recommend.

Never worked
It has never worked. The bottle has still very very cold after setting the timer for the longest setting. Bought when I first found out I was pregnant and couldn’t return.

Stopped Working In 2 Weeks
I bought this bottle warmer ahead of my daughter's due date. She delievered her baby and has only used the bottle warmer for 2 weeks and it has stopped working. Completely unacceptable and a waste of money!

Great product and great initial warranty if the heating gets dicey, they will send you a new one if there is a defect with minimal questions asked (you just ship the old faulty one back). Highly recommend!

Needed a replacement bottle warmer after our original started leaking. The new one is working great and haven't had any issues so far.

I loved this warmer until it stopped working. It burned a hole through the bottom on the warmer and stopped working after almost 2 months. So disappointed.

Great bottle warmer. It never overheats breastmilk.

short lifespan
It seems these bottle warmers stop working really fast. We've gone through a few, even with proper care being done. The water stops rising and bottles stop warming up.

We had gotten this bottle warmer first as a baby shower gift and after 3 months the water pump went out. Reading through the instructions we just assumed we probably needed to clean it more and we liked the warmer so we bought another. Making sure this time to follow all cleaning instructions. 3 months later the pump goes out again. Not worth the money to have to buy a new one every 3 months.
