This shelf is perfect. I am using it to put my microwave and toaster oven stacked on my counter and I used the top shelf for extra storage. I read a couple negative reviews and I think the issue is not understanding how to put these kinds of shelves together. The plastic clips have to click into place and and be snug and not move it takes adjusting them a bit but then they do click in without issue. The shelves sit on top and can then be pushed into place. If the plastic piece is sliding you didnt click it in properly. It is very sturdy, dont let user error discourage you. I guess the instructions could be more clear but to me it seemed pretty self explanatory. Watch a YouTube video if you cant figure it out but they are a good size and sturdy. Very happy with the purchase.
