Broke only a couple months into the school year.  I expected the cheap plastic head piece to give away first but the plug got stuck in my son's chromebook.  I won't be purchasing again.

This backpack was purchased for my 2nd grader.  When it arrived I admired the strong canvas structure and the tough bottom.  I was happy to see that the bottom of the backpack wasn't made from canvas- perfect for it getting dragged around on the ground, thrown in lockers, etc. Her first day of school was Sept 10th.  By the end of September the little kitten paw on the small zipper had fallen off.  Easy fix- it's just a metal ring.  On Nov 30th, one of the zippers broke on the main compartment.  No big deal- there are two zippers for a reason.  Well yesterday, Dec 2nd, the 2nd zipper broke.  Mind you, the entire zipper.  It would cost more to repair the zipper than to buy her a new backpack.  However, kudos to the design.  My daughter loves the look of the backpack so much I have to buy her this exact one.  Grrrrr...

...and it didn't even have frequent use for most of those months.  If it was only going to last a few months it probably would have made more sense to buy one of the really cheap ones that get complaints about only lasting a few months.

UPDATE: I first gave this product 1 star based on the comment above, but am so impressed with the customer service, promptly offering to send a replacement, that I have changed it to 4 stars.

The straps fell apart.  He got in May and by the time school was over June 12th the straps was split apart.  Trust me he wasn't carrying a lot a folder and a book.

Just a few short months after I purchased the cable it broke on me. I really like it before it broke because of the length I was able to do homework and have two screens but now that it is broken I am unable to do that

It almost made it a whole school year of intermittent use before falling apart, but now I find myself buying my child a new set. The ear cushion came off and there were exposed wires underneath, and after that was fixed there seems to be some sort of short in the wire and the sound cuts in and out.

I was really happy with this when I got it but after only a couple months with this, I sat on it to put my shoes on and one of the legs completely split in two. I didn't sit with force and I am well below 200lb...

My son loved this backpack while it lasted which was about 2/3 of the school year.  He really liked being able to roll his bag around when it was heavy with books.  It was spacious enough for everything he might need at school except for his lunch box.  I probably won't purchase again since it didn't last long, but not bad for a rather cheap backpack.

Purchased this on February 17th. My daughter has been using these 3 to 4 times a week. Saturday (3/19) she had her swim meet. She adjusted her goggles and they broke. Not very happy to only get one months use from them.

This case broke only after a couple months of having it. I was not especially rough on the phone and thought it would last a little longer than a few months. The plastic cracked on the bottom by the lightening port and at the top by the camera. I picked it up after these cracks had already happened and the the whole plastic piece on the top just fell off. I will be trying a different brand of phone cases next time around.

Works great until it breaks into short sections after a couple months with 3x/week use for 3 minutes. Worth the price though if you use them for kids that love them (my special ed kids that I tutor love them during sensory breaks). You get several pieces and these things aren't built to last anyway.

14 days out from the end of the school year and this box just couldn't last.  First one of the hinges cracked, but it was still usable.  Then one of the locks broke off, but it was still usable.  Finally the other hinge has completely broken apart and it's no longer usable.  It was carried inside a lunch box all year, but that didn't do much good apparently.  On a positive note, it didn't start to fall apart until maybe a month ago, but once it starts it goes pretty quickly.  Will be looking for another product to use next school year.

I purchased this for my classroom and loved it in the beginning! Pencils sharp, quiet and sturdy. Two months later the sharpener is broken and won't sharpen a thing.

I secured a grant to purchase 24 headphones for my classroom less than a year ago. Within a few weeks, one of my student's headphone plug had broken off into the jack of their ipad. I initially blamed the student for being careless, but then it happened again, and again, and again. Less than a year after purchasing 28 pairs, nearly 2/3 of them are broken. These are marketed to be durable and great for a classroom, so I thought the company might be willing to help replace them. When I called the manufacturer I was told that the headphones only break when they are being unplugged incorrectly. They must be pulled straight out. If there is any angling, then the plug will break. Sorry about your luck. I work in a very high need school, with over 75% of my students living in poverty. There is no money to buy more headphones. I will not be able to replace them. It is very disappointing that they are not willing to stand by a product that is described as the "benchmark headphone" for schools.

Broke after 2 months of using them - they no longer connect to any Bluetooth sources. The plastic housing also did come apart a couple of times while I transported it in my bag - not a huge deal since it snaps back together relatively easily and intuitively, but it's just an indication of the quality of construction (of course, this was one of the cheapest bluetooth headphones around when I bought it, so that's to be expected...).

I bought these in July 2016 for my daughter to use in the classroom at school during the 2016-2017 school year. They were great for the school year, never had an issue. We brought them home for the summer, were rarely used (as she has other ones she uses). Now that the 2017-2018 school year has started, these are no longer working. There is no damage to them and the one year warranty expired less than a month ago. I did not get the 2 year protection plan because I figured these would last a lot longer than a year. I did not reach out to the seller or company to address the issue because she needs headphones for school tomorrow and don't have time to wait for the replacement process.
