Overall, the physical product itself seems sturdy. It is made of a hard plastic like material. The size seems appropriate for shelves. I was excited to put this shelf together and see how it held up. I was disappointed to open the box and discover no directions. I have put together many things over the years but this clearly needs some instructions. I lowered my review due to not having any directions in the box.

Great product, would have been a five rating but as it is not in a box, they should’ve noticed that the package was dropped, and one of the shelves was smashed on the end. In-store pick up employee loaded it into the back of my SUV without me noticing the cracked piece and I drove away.

The Member's Mark 5 Tier Heavy-Duty Ventilated Plastic Shelving unit is a work beast! First, it was super easy to assemble in minutes and NO tools needed. I love how sturdy it is, the interlocking shelving feature rocks, and the leveling/adjustable feet that allowed me to accommodate my unleveled basement space to our needs. The shelves are 48" wide which is bigger than other ones I have. Makes it easy to store my big 27 gallon tubs on it...and the shelves hold up to 200lbs each! The packaging was minimal and love that it is made with recycled plastic. A must in your basement or garage!

Nice shelf just be aware not at 27 gallon totes will fit The Sam's ones will and mine from Lowe's do but not the ones I bought at Menards

So easy to assemble. I bought 3 and linked them along a wall of my garage. The width and depth will accommodate many large bin sizes.

Easy to build very durable!

Plenty of room to place on the shelves

Sturdy, easy to assemble, multiple options for height.

I bought this to store all my bins that I bought that we’re supposed to fit in there and they do not fit

Very happy with purchase and will recommend to others. I especially like how wide they are and easy to connect together.
