I recently bought these on sale at a great price to use for storing school curriculum and records. They were very easy to assemble. Unfortunately between the store and my van they received a light sprinkling of rain and this may have affected their durability. That being said it is hard to tell just how sturdy they are. My suggestion: shop for these when there is no precipitation in the forecast. All in all they do the job I want them to do and I got them at a great price. If I can get them again at the same price I will buy more.
It was good inexpensive. It was good quality. It was easy to put together. I got it for less than a dollar a box about which made it a great deal!!!!!!!! However......... For every...let's say ten I put together one rips..... but they are great for moving and storing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Sorry for the extra exclamation points I had to write more than 400 characters.
The price was considerably less than the other name brand boxes. They aren't quite as sturdy but they do the job quite well. Not sure if they will stand up to multiple years use - or storage in off site facilities (Multiple handling and moving). But for the cost I will just buy more next year.
