## Customer Reviews

### ⭐⭐⭐⭐⭐ Great quality!!
*by A***7 on July 7, 2025*

I’ve used this for several years with my air conditioners. I love that it is white like my window frames so it doesn’t show from outside, and it is thick and insulating.

### ⭐⭐⭐⭐⭐ It adheres and does its job.
*by S***. on July 14, 2024*

Just make sure the surface you use it on is clean and dirt and grease removed. I used alcohol and did it twice to make sure it would stay adhered. It’s nice to be able to seal a drafty spot, or around your air conditioner.

### ⭐⭐⭐⭐ Okay
*by #***E on May 31, 2022*

The product is flexible and formable. Compared to the black product I ordered similar quality. Though I prefer the more robust black option.For the money the sponge like grayish product is better. It’s longer. Flexible and moldable. Better price for longer more versatile option.Though this is durable for three years the package states. Like the cheaper products. It’s too short to do much anything is why I removed a star.Using this for a portable air conditioner window mount exhaust. Or for the wall mount into the duct system.⭐️⭐️⭐️⭐️
