I’m unfortunately very disappointed with this bottle warmer.
First, it doesn’t heat consistently. Often it shows 70 or even 80 degrees, but the formula/milk is still completely cold. That makes it very unreliable, especially when you need to prepare a bottle quickly.
Second, it leaks easily. If I place it on the bed and it tips over, the liquid spills out. It really should have a proper sealing system like a normal bottle to prevent this.
Finally, the device turns off…

Disappointed

Don't buy this!
This is the worst bottle warmers I've ever had. Truly no way of keeping it sanitized unlike the Papblic. The lid is also so flimsy and broke within the second use. Absolutely regret asking for this on my registry. You're better off with a different one or just sticking the bottle in a hot cup - much more sanitary than this mold inviting nightmare of a bottle warmer.

No for me
I have been using this for four months and there is rust in the bottom. I tried to submit a warranty but waited online for 2 hours and then they wouldn’t give me one because I received it as a gift from my shower.
Also, it takes forever to warm.

Love!!
Love this warmer. It is perfect for my picky little guy! I love how easy it is to take with and the charger being a very common charger to use!

Práctico y rápido
Compré esto y el termo enfriador/congelador. Ambos son excelentes. El calentador te da para calentar muchas tomas, 4 o 5 tranquilamente (aunque si la leche esta muy fría o calientas agua a una temperatura más elevada de 37ºC quizá no puedas calentar tantas tomas). Lo único que me gustaría sería poder meterlo en el esterilizador pero con un buen lavado y secado ha sido suficiente en nuestro caso. Además al cabo de un tiempo apareció oxido y pudimos cambiarlo por otro. El servicio postventa es excelente.

Tolle Verarbeitung und ein absoluter Gamechanger. Ich bin absolut begeistert vom Produkt. Dadurch sind wir als Familie aber auch mein Freund, wenn er alleine mit der Kleinen ist, total mobil.
Die Handhabung ist einfach, die Milch schnell auf der richtigen Temperatur und die Reinigung geht schnell.

Great product and even better customer service
I ordered the Momcozy portable bottle warmer and was really looking forward to trying it. Unfortunately, UPS marked my first package as delivered even though nothing ever arrived. I reached out to Momcozy, explained the situation, and once I confirmed at the end of the day that the package still hadn’t shown up, they immediately sent out a replacement with no hassle at all.
The new one arrived quickly, and the product works exactly as expected, super convenient and perfect for on‑the‑go…

A must have
Love this product! Uses it daily, both at home and away.
Perfect for when someone also are babysitting. And the easiest to use.
Don't know what I did before I got this one.
