I was looking for something to fill a corner in my entryway and the Sziqiqi set caught my eye. The 26 inch height is perfect for adding some verticality to the space. They feel pretty sturdy, though I did add a few decorative stones inside just to make sure they wouldn't tip over if my cat gets zoomies. For the price, you really can't beat the style.

idk guys, i think these are overpriced. The installation instructions were super confusing and it took me way too long to get it right. Honestly didn't notice a huge difference from the generic brand i used before. Prob won't buy again.
