I read the reviews before purchasing this warmer/cooler and found several mentioned the cooler lid doesn't "close/seal". I would like to say, it does, you have to have the handle in the up position, in order for it to close properly and prevent milk from getting warmer faster.

The tubes for water measurement are kind of pointless. Don't go by it. They never have made it warm enough based on the measurements. I have to just add water and eyeball it!

Still, an excellent product!

I really wanted to love this product but the cooler isn't that amazing. The ice pack might keep everything cool enough for 4 hrs but definitely not 8 hrs. I ended up using the cooler and ice pack that came with my medela pump. It keeps everything very cold all night long.

I would be fine if they made the cooler electric to keep everything cold.

Even though I am breastfeeding, we have been using this occasionally at night so Dad can feed and I can get a little more sleep. It has worked great! Quick, easy, bottle is warm by the time the diaper is changed. We did find that it took more water than the guidelines recommend to heat a full bottle, so you may have to play with it a little. We also do not have the nipple on as it heats because the nipple becomes too hot, and by the time it cools down, the bottle is too cool. Just put the nipple on at the end, give it a shake, and it has been good to go!

It's good for the price. The ice pack is a small plastic bottle that you freeze. I find that it's not enough to keep milk cold all night so I add a small group frozen gel packs. The warmer is fast but the water measure is inconsistent. I would put 4mins for the same amount of milk and sometimes it's too hot sometimes not enough.

I read the one star reviews and I'm going to give my take on them.

- it takes too long.
4 mins for 4oz. The vials of water needed are prepped in adv. If you do this it saves time. 4mins vs warming water on the stove and waiting for it. Takes long?! Also know your baby's hunger cues. Intercept with a bottle before it GETS to screaming and you won't have that problem.
- You need to unplug it to stop it.
It stops on its own. It will stop when the water you added is gone. If you add the CORRECT Amt of water this is no issue. It comes with directions. Use it. I have never had formula too hot. Not once. As your baby grows you will need more water for larger bottles. This is obvious.
- the cooler isn't electric.
Did you expect it to be for 20 dollars?! The ice pack it comes wihj works perfectly.
- doesn't work with Dr Browns.
I won't fully dispute this one, but I personally have had no issues with Dr Browns. It comes with a ring you need to add on for slim bottles vs wide bottles. I use the ring and take the cap off the bottle and don't have a problem. Maybe because I remove the nipple?
-too complicated.
It's really not. Add correct Amt of water in directions. Press button down. Wait till light shuts off. Done. Not complicated.

I've had this warmer for 3 weeks and it's been lifesaving. I take it up to bed with me and my baby at night for my dresser and I'm no longer 4am step running. Only upkeep is cleaning mineral deposits from the unit and basket which involves rinsing wihj hot water and a paper towel. Takes a few mins a few times a week, and remembering to refreeze the ice block.

It would be nice if it came with TWO ice blocks. That's my only complaint.

Otherwise this is a great warmer for 20 bucks.

UPDATE:
ABOUT TOMMEE TIPPEE BOTTLES!
We recently purchased tommee tippee bottles for my son. We added the water we were told to via directions. 4. I heated the bottle and it felt REALLY hot. When I tested it it BURNED me. If I wouldn't have tested it my son would have been badly burned.

We realized this is due to how wide they are. Wider than usual wide bottles. There is NO gap to allow the steam to escape so the bottle heats up more than the usual bottle. ESP if you leave it in the unit a while after it heats up. It just continues to heat.

Also they do NOT fit in the cooler. Not even one. The cooler is useless with these bottles they are just too wide. We hardly ever use it but if you plan on using it a lot you might want another warmer If you're a tommee tippee user.

It can still be used with some precautions.
- our formula Amt says to add water to 4. We now add to 3.
- after the unit shuts off remove the bottle immediately.

Basically you have to experiment to find the proper water level. It will differ depending on how much your feeding is at the time.

Just wanted to add this because my baby could have been hurt.
