## Customer Reviews

### ⭐⭐⭐⭐⭐ Good one
*by  on Reviewed in the United Arab Emirates 13 November 2024*

I tried 2-3 other brands for closing my duct holes...Pressing the knob is easy and the foam expands greatly..Since it is 500Ml easy to handle too, still it gives the effect of 750Ml

### ⭐ Substandard Product, Even at this Price
*by  on Reviewed in the United Arab Emirates 11 June 2025*

As many have said, this product is full of problems. Mine did arrive with the hose attachment, but that was about the only positive. The can felt half full, even though it was a brand new can. Followed all directions, and attempted to fill the gap in the door frame. The foam came out very slowly and has minimal expansion. I had some excess leak from the straw once the can was empty, and it probably only expanded 10-20% from the wet size out of the can. The half full can was used up in about 10 seconds and didn't even fill 30% of the door gap I needed to seal. Other cans of this size, by other manufactures, would have done the exact job I needed (based on past experience) and I would have had a little left over. Purchased another can from a different manufacturer, one I know is a better product, and will finish this door right. The cost is low on purpose as this is a "get what you pay for" product. Not worth it.

### ⭐⭐⭐⭐ Great product.
*by  on Reviewed in the United Arab Emirates 4 May 2024*

Helpful. But it gets dry inside the dispenser straw
