Loviga Universal Sliding Door Seal Kit for Portable Air Conditioner and Dryer, 100% Sealing Dual Hose Support AC Door Vent Kit, 10x75~91 Inch Length Adjustable for Mobile A/C

This seal kit definitely adds to the operations of the Portable A/C unit. It was simple to install. I definitely believe if anyone reads reviews, they might be questioning if it’s actually necessary.It is definitely worth the price. I highly recommend this seal kit

Got this to keep the smoke from my laser cutter from blowing back into my sliding door and it works perfectly. The drawstring on the exhaust port secures and seals around the laser exhaust hose and keeps the smoke and smell from coming back into the house. If you have any craft machine that needs an exhaust, this is a must buy.

Not exactly made to keep heat out, but if you first cover the opening with foil insulation and cut a hole for the hose, it is a great alternative to the fixture that comes with the ACs normally

Good product, perfect size and easy to use

This product didn’t even last a single day. The adhesive strength of the double-sided tape on the Velcro is far too weak. The Velcro itself has an insanely strong grip, but the adhesive that connects it to the wall is so weak that after I attached the hose and went out for a bit, it just fell off. I was so frustrated that if the guy who made this was next to me, I would've punched him. (Of course, if the guy was a Giga Chad, I'd get wrecked, so I wouldn’t.)

Velcro is strong and the idea of the design is great. However, the double sided tape is weak and will not stick to the window frame. Fell ofg within hours of first use. **UPDATE ** changing this to 3 stars because the seller reached out quickly to offer troubleshooting and a resolution. I declined a new item but I think their customer service warrants a raise on their rating.

Good quality, easy to install. Works perfect!

Good!! Just enough to cool immediate area
