Bought this on woot a couple of weeks ago. Mostly happy with it. Provides a lot of flexibility for how you set up your drawer storage. However, mine did come with a cracked corner. I wouldn’t call the weight of the plastic flimsy, but I’m not sure sturdy fits either. Somewhere between. Didn’t bother to return it cause it’s in a drawer and I put the broken corner towards the back.
FYI the pieces don’t slide like some other similar products. In fact, they’re not connected at all. Three separate pieces that fit together. There are rows of interlocking teeth that fit together to keep the trays where you want them.
I’d probably buy it again.
