It’s a good warmer and you do use your own bottles so less to wash and clean up. It comes with adapters to help fit your size bottle. Very portable and light weight.

This bottle warmer is small and portable. So, it's good for travel. It has 3 heat settings: 98⁰F, 104⁰F, and 113⁰F. This warmer comes with a usb-type C charging cable. It also comes with two bottle adapters, that work with regular bottles, and bottles with the next size up openings (36mm and 50mm). I normally use regular size bottles with the small openings. I have one other bottle (with large size opening) that doesn't work with the attachments that come with this warmer. I don't know it's size, as far as mm. But, I measured it in inches, and it's opening is just over 2 and half inches. I showed this bottle, and a couple others in the attached video. I hope this helps. 😊

I compared this next to my Baby's Brew. I made sure both units were 100% charged, both were turned on at the exact same time, and that both were heating exactly 5oz in Medela bottles to 98 degrees. This unit finished warming literally RIGHT before the BB did, so warming time is basically the same. This warmer only heats 3 different temperatures while the BB heats 4 (it has an 80 degree temperature that this unit doesn't have) but that's not a deal breaker in my opinion because I've never used the 80 degree temperature. Price points are also very comparable for the warmer itself but the pro to this is that it comes with attachments whereas the BB does not and you have to purchase those separate at $10 a piece. I will note the BB attachments do work with this warmer though and I know because I mainly use Tommee Tippee bottles and this warmer doesn't come with an attachment for it but I tried my BB adapter with this and the fit is perfect. The piece that goes on the top between uses (to keep it clean) is better on this warmer because it screws on instead of those suction rabbit ears that are a pain on the BB and this is also more of a compact unit.Both warmers get the job done. I did notice this said it fit the "regular" Nuk bottles but it must've been talking about the skinny neck Nuk's because the "regular" version of Nuk IMO is the size between the narrow neck and the Simply Natural bottles and that middle size does not fit. I would absolutely recommend this, especially if the adapters fit the bottles you're already using.

This bottle warmed is wonderful! I live the option to attach the bottle. Cleaning is simple. The digital screen is a plus so you know the temperature! I recommend this.

Love this! We got this for our new baby and it's great for on the go! I love that it heats the liquid and not the bottle so as to not get micro plastics in the milk.

While this only holds a charge for about 2 bottles, it’s such a lifesaver! It heats the milk appropriately and I had no issues with leaking.

My little one doesn’t like her formula and milk to be very hot, so we were excited to find a device that gave us options for temperature. This thing does really well with those, and it seems to be pretty consistent with each bottle. We’re very happy with this product.

Great product. No issues so far.

This is great if your baby only takes warm milk. It is easy to use & attaches to a variety of baby bottles. Very affordable & easy to clean too. It doesn't take up too much space either.

I have used this with both my Tommee bottles and my evenflo bottles and had no issues. It heats up the milk at the same time it takes my plug in warmer too. It doesn't take long to charge and the charge does last awhil. I just stopped using it because I'm so tired of carrying extra things around with me in all honesty. But it does work well on both large and small necked bottles. Easy to clean off and reuse.
