These are ok if you are going to use them for storage where you don't need to access what's inside on a daily or even weekly basis.  I purchased them to store shirts by size that I need for customer orders.  I am opening, closing, and stacking on a daily basis and I'm noticing some wear and cracking after just a couple weeks.  These do not stack level on top of each other either.  To save on wear and tear, I'm only filling them about half full as to not test the strength of the plastic and hope to keep them around a bit longer.  Two of the lids shattered in the first shipment and Wayfair was wonderful about sending replacements immediately!
