After 2 - 3 uses, the handle ripped off. Also, when you pick up the lunch box by the handle when it is filled with lunch, the top opens as the velcro is not strong enough to keep it closed.

I purchased this thermos for my sons lunchbox.  He stated that his food is still hot at lunch break.  I plan to purchase the longer size for my husband.

The swords were both cracked within 2 days of play.  My son has been begging me to order new ones.

My 9-yr-old son LOVES Regular Show (as does the whole family). This lunchbox is the right size and good quality. I love metal lunch boxes because they clean easily and last the whole school year. It came with two added bonuses: the travel mug and coasters! Doesn't get much better than that!

UPDATE: (8/21/14)

So after my son actually used this lunchbox on the first day of school, the lid began to detach from the box. I contacted Amazon and because it's sold by a third party they could not offer a replacement. They did, however, issue me a refund and told me if it was still available for purchase online, I could reorder it and they would allow one day shipping at no charge. So I did just that. Unfortunately, the second one is doing the same exact thing. The product although looks great, is made of poor quality. Would not recommend.

Using it from last couple of months for both of my kids school lunch. In the beginner it was retaining heat for more than 5hrs. Over the time its not retaining that long

My 21 month old toddler brings lunch in this container to lunch.  I usually heat up the food around 7 and he eats around 11:00.  The teachers say the food is still warm by the time he eats it.  The reason for the 4 stars is because the original one I ordered broke after only a couple of weeks.  The lid locks in place and will not open (EVERYONE tried to open it).  It keeps making a clicking sound as you turn it, but it just won't open until it's completely cooled down the next day.  I returned the old one to Amazon and got a replacement, and the new one is still working after 2 months.

I purchased it for my four-year-old son (he is now 5 years old). I prepare his lunch everyday and pack it at 6:30 am.  He has lunch at 11:30 am.  My son states his lunch it a bit cold by the time he has lunch. I checked it once and it was warm-cold. Hence, I avoid preparing sauce based meals. I can't include a salad or a cold entree since it gets too hot (possibly during the first hour). I have noticed the salad cheese (Manchego sheep's cheese) to get a bit melted. The main problem I have is the fact the lunch box is difficult to transport; thus, I place it sideways inside a standard American lunch box for kids. Hence, whatever I cook gets all mixed up ... and of course my son does not like it. The containers are easy to hand-wash (I do not have a dishwasher).  The quality of the plastic is really good, it is almost a couple of years I use the plastic containers and they are in perfect condition. Notice this is a lunch box for kids, so the containers are small.

I really like this lunch box. It's perfect for my 2 year old son (we've been using it from about the age of 1) though I would think that it is too small for an older kid (5+).  Everything stays in it's place.  It fits in the skip hop zoo lunch bag along with a freezer pack.  We use it a few times a week and usually hand wash.  The side of the inside part has cracked though, which is why I docked a star.

Bought this for my son to take in his lunchbox. He's in 3rd grade and they eat at noon, so it's about 5 hours from the time we put food in thermos in the morning until he eats lunch. So far, it has been a neat little thermos and he loves it. It hasn't leaked a bit and keeps his food "medium warm" (per my son) which I think is pretty good for 5 hours. I plan on buying another one to rotate out with the old one.

My 3 year old broke one of the shields after 2 days.  I'm looking at something more heavy duty.

The zipper broke the second day that my son used it for school. He now uses a paper clip to pull the zipper open or close. The product is not durable!

Looks awesome but my son took it to school and after just 3 days it ripped and I had to sow it up for him..

Well the second day was empty, and I guess it was a good way to teach my 2 year old disappointment. Haha. We did get 24 items though because the next week one door had 2 stickers inside.
