I bought this bathroom shelf on Amazon and overall, I’m fairly satisfied with the purchase. It is sturdy and holds my items securely without wobbling. The assembly process was straightforward and didn’t take much time. However, I did expect it to be a bit wider based on the pictures, so make sure to double-check the measurements before ordering. I also wish the overall quality of the materials was a little better, as some parts feel slightly less durable than I expected. That said, it still does the job well and serves its purpose. It’s not a bad purchase, especially if you’re looking for something functional and affordable.

Great shelves. As you’d expect - and mounting is just fine if you pay attention and hit some studs. I’ve got my wife’s plants on these for over a year with no problems.
