over a year and these are still going strong and damage free

we got these to use for storing the household cleaning supplies under the kitchen sink and they hold a lottttt of products and despite the fact that they are essentially pulled in smd put from their place on each side of the cabinets to get access to the stuff more towards the back of the racks despite the weight of the contents they've been holding up theres been zero breaking down or wear&tear from ehat we can see, i wish they were designed  to have heavy weight bearing wheels on the very bottoms and theyd likely need to be those 360 spin wheels as well it would be able to essentially get access to everything despite the weight stacked on each shelf and also make sure that everything is easily accessible regardless of what you are doing as an organization method, that's what I do wish these super strong durable and easy to use shelves were designed with the wheels for easier maneuverability with people who are varying in different levels of strength can benefit from. however even without having the ability to be dragging thr shelves back and forth under the sjnk cabinets while filled up completely  and not  have to worry about possibly breaking them on accident. but overall we use these constantly and then quality and durability and storage spaces are extremely well made for plastic shelves. id buy more if i genuinely needed more for other things to get stored in a similar way, id absolutely reccomend testing them out and seeing how they work  for yourself i doubt that you)l find you are not likely to regret getting them
