Review: Works. Velcro sticks well. - As expected, basic effective product. Worked with stick velcro before and found the velcro surprisingly stick, even after being exposed to summer heat. Do have some of the velcro peel off at first, but corrected it hand no trouble after that. Better than previous experiences. The higher vent is important, as many aircons suggest putting vent higher than aircon.
Review: Great door curtain for my portable air con unit - We are experiencing super-hot weather in the UK at the moment and buying this curtain turned out to be a wise move. Before buying this I had a piece of cardboard attached to the end of the pipe and used to try and wedge it in a window but there was so much air flow leakage, it wasn't a good idea. I found the install of the curtain really easy applying the velcro tape, its really sticky so no problems with it coming off. The fit was slightly too big for my door but it didn't matter as managed to make it seal. The zips seem good quality, not had any breakages yet and been using it for a few weeks. Overall an excellent doorway air con curtain.

### ⭐⭐⭐⭐ Does the job but a bit of a faff
*by R***B on 19 June 2025*

It works just fine once installed but is a bit of a faff to get it around the window just right. Always gets a bit tight in certain spots and the adhesive for the double sided velcro only really lasts for one summer. As long as you are happy to have to re-do it once a year (which on reflection isnt really a hardship) then its absolutely fine.
