Heavy Duty Non-Slip Door and Window Stopper

The item is much too large for a normal window - I tried it on all my windows and it doesn't fit into the gap as shown in the pictures on the product page.

Hello, good rigid product

Perfect

Very good product! Thank you!

I am happy with it. great for a balcony door too. only works in the corner of the window or door!

A decent stopper, the shape is very useful. durability is not ideal with this material. its 3d printed plastic. it will break stopping heavy doors on a windy day. but for this price you can buy a few.

Very simple, matches the description and photos. For now it seems to be fine and I see it as durable 💪🏽

Very useful parts that fit my windows perfectly.

The product matches the description. I recommend it!

It holds up without any problems and works properly.

performs its functions
the balcony door holds open
and overall it looks like an art object

Ordered on March 12, 2026, received on March 21, 2026 in France.
It's made of hard plastic, I thought it was rubber when I bought it but I didn't read everything.

It fulfills its function. Fits perfectly.

It's nice, looks sturdy. Just right at a 90-degree angle.

Everything matches the description. I'm taking it a second time.
I recommend

To be honest, I had doubts about whether this would fit my balcony door and whether it would be stable enough. It fits perfectly and holds the door at a 90-degree angle stably and without damage. I think the price for this well-made product is too low. I recommend it. 👍🏻
