Brynnl Portable Air Conditioner Window Vent Kit, 16.9''-55'' Adjustable Window Seal Window Vent Set for Mobile Air Conditioner Sliding Vent Window Sealing Bracket Kit fit for 5.9'' Exhaust Hose

Got this as the kit that came with the air con wasn't very good. This fitted there bill. A good purchase.

This arrived as advertised. Correct measurements. Good quality. On time delivery. Multiple sliders to allow you to fit awkward style windows. My only criticism would be to include directions on using the screw fixings as it’s not clear.

This isn’t great. It says it’s suitable for windows from 17 inches. The way the two slats fit together there is a strange of about 6 inches where you need to cut a chunk off the end. If not the second slat hits the hose fitting and doesn’t go short enough.Second problem is it’s too shallow for a secure fit in my windows. If it was an inch deeper it would be better. The hose fitting is right near the edge of the slat so it floats more than fits the window. To stop this I’ve actually fitted it in the middle of the window frame and not at the front and used a cloth to bridge the gap.This is more balanced In my window. It’s not sealed. Once the sash window is open it also creates a gap between the two sections of glass.This is doing it’s job in as much as it’s better than the cardboard I was using. It’s probably better than the zip fabric versions. It’s serving a purpose but it’s not perfect.

Works but have had to tape it into my window as no screws arrived to hold it together. Still works to vent air out

If you have a sash window and a 5.9 inch hose, this will work fine.Easy to install - though no instructions included.

it sort of works and a but fiddly to set up - but considering the cost it does the job ok - i can think of many ways to improve it with a drill and some rivets
