Mardili Large Window Sill Suction Cup Shelf,10 Inches, A Pair

Good thing I decided to try this shelf out before I actually put a plant on it!The first time I put this shelf up, it stayed up for a few days and I thought "ok not so bad", despite the fact that it is pitched forward at an awkward angle. There is also an unnecessary piece of plastic in the back so that the shelf itself does not sit flush to window.I DID NOT place a plant on this and I'm thankful that I didn't! It sticks to the window for maybe 60 seconds before it falls down! Wish I wasn't past my return time for this otherwise it would go back! Waste of $20

Fell of the window and cracked. Don't buy.

The suction cups did not stick at all. I have this on a window in my classroom displaying small trinkets (less than a pound). They both fall down a a daily basis and have broken from falling. They have also damaged the items it was holding. I would not recommend.

For the amount of money the shelves cost, I thought they would hold much better. Not happy. Obviously you can't put a bowling ball on it, but you can't put anything heavier than one of those dancing solar figures from the dollar store. Considering returning.

I am using this to hold three bottles on my classroom window to start plant cuttings. It is holding securely.

Holds up my small potted plants very well. The suction cups are strong... maybe even too strong. They are hard to move once on the window. That would probably be my only complaint. Other than that... they are great!

I put these on glass block windows above the kitchen sink for some easy extra shelving. One of the shelves has fallen a few times while the other has stayed up. I've only put light plastic things on it so far.A bit pricey for what they are, and I wish the the suction was stronger

Alternative use here. These shelves work great for adding addition space to my snake's terrarium. Excellent suction power, sturdiness, and easy to install or move. My snake enjoys having the arboreal space to move about and explore.
