Bests & Worsts Reviews from Amazon

September 2018. The containers are well enough with straight sides for files to fit in nicely. The reason I didn't give it a better rating is because the lids are lightweight, flimsy and non-stackable where I wouldn't want to stack more than two together. I don't think these lids can take the weight of 3 stacked together. And even worse, they do not lock into place when stacked which is a major disappointment. The boxes slide around easily on top each other when stacked which is a ridiculous feature for file boxes. The lids are not as advertised. The lids I received are from a different mold, having no inner track for the bottom of boxes to sit. Heaven forbid someone bumps into them and all your top boxes slide off and fall over and your files spill out. I'd rather pay more money if they would improve the lids by making them stronger, more durable and stackable. In using plastic boxes for decades, I find it's the lids that usually break first. Unfortunately, a customers who purchased these in 2016 and 2017 received well made locking lids so people are buying this based on their 5 star rating. For my purchase, they obviously went downhill in quality and used a different manufacturer for the lids, cutting corners and making this a less than desirable purchase. I would prefer to return this item but it's past the window, so I'm stuck with it. I advise people to choose differently.
