BuenoUsamos esto para el diario calentar nuestro almuerzo lo recomiendoDue to covid they have removed all the food prep applications from our office break room. There is a cafeteria at my work site, but I don't want to buy food every day. No issue with bringing a cooler to work, but I needed something for when I wanted to eat something hot. First week I used it, no issues. As long as I put hot food into it, it keeps the food hot.Hubby and I tried it on a short trip, using the 12 volt cord. Worked great. I do recommend putting it in a cooler to keep it warm, if you have to leave it in the car and don't want to leave it plugged in.He wants one for when he is on his work trips. That was the reason I bought this one, because it had the AC and the DC cords.Very happy with it. My only issue is the top. I really don't need that spoon and the extra pocket its kept in really seems to be a waste. I would have preferred a smooth lid and no spoon. But for the price, its a small complaint.This is a wonderful product and it solves my meal problems. I work in a construction site with no access to restaurants. There is only one microwave and takes a long time to heat up my lunch. I do not want to eat cold sandwiches. This container allows me to keep my food warm. It is warm, not hot. It will not overheat. It does takes awhile to heat up, approximately 30 to 45 minutes. But, all I have to do is plug it in when I arrived at work, and leave it there. It keeps warm until whenever I want to eat. Put in cooked food because it is not hot enough to cook. I put rice with beef stew on top. Also, a chicken noodle soup. Plugged it in around 7:00am, I eat at around 10am. It is ready to go. Warm and tasty. It does not alter the texture of the food, even better than microwave. Again, it only takes a little bit of electricity, like a 40w bulb. It comes with a stainless steel container. Easy to clean. Yesterday, I left the container in the fridge overnight, the next day, it warms up fine. Important, do not leave the whole unit in the fridge. You do not want to get the plug wet, remember condensation, that can make the electrical wet inside. Bad! Don't do that. Just leave the container in the fridge, and the heating unit outside. I used to have Stanley which is very good at keeping food warm, but still, it is just insulation, it will get cold somehow. But this one keeps warm for as long as you want. Even when I am driving, it has a car plug. Get the version with both car and home plug. You will find it useful. THIS IS AN EXCELLENT PRODUCT!!Muy práctica pero no calienta muchoI purchased this as a gift for a friend of mine who's a truck driver who wanted to eat warm food while he was working. He was excited to use it and took it to work the next day after he got it. Unfortunately he was unable to use it because he couldn't connect the electrical cord to the main warmer part. Not only because it was hard to do (it doesn't plug together easily), but because the one we got had a broken piece inside. I ended up have to contact Amazon to get a replacement for the defective product. Once we got the replacement, we plugged in the cord to the device and taped it on place this way he wouldn't have to struggle with it each time he tried di plug in it (because as I mentioned earlier, the cord wasn't easy to plug in to the device). So one problem hopefully averted by doing it, but he ran into another problem. He put soup inside but the lid is not air tight, so some of the soup leaked out even before he got to eat it. He said it heated up the soup but it did take quite a while. Also be careful once it had warmed up because he said that bottom of the device gets hot. Overall I would say it's an ok product. Not necessarily as good as I thought it was going to be.This item came in handy for my husbands lunch. with only one microwave and about 40 people trying to use it at the same time. He gets in his car heats it up for a few minutes and is able to enjoy his lunch warm.This product is really good but after 3 week it's stop working what should I do please let me know
