Great cost saving item

Installation wasn't as bad as long as you take time in installing tape. Was hoping it will shrink with heat, but surprisingly film did not shrink with hair dryer.
Easy install and definitely helps a little with the bills

Easy to install. Definitely isn't as good as getting good double paned windows or patio doors, but definitely helps enough to justify the cost of the kit.
Not great.

This doesn't work very well, definitely still feels cold/drafty near my Windows. So disappointed. 2 stars because it's easy to use and hoping it's making SOME difference...

This works as advertised. It is very easy to install (search YouTube for instructions) and l have not had a problem with it staying in place. This is the second summer I have used it and I will keep using it as long as they keep manufacturing it. Thumbs up!
Recommend finding ways to keep cat away

worked well until my cat tore a hole in it. Recommend finding ways to keep cat away. Also, pull the plastic tight by hand because otherwise, the hair dryer can only shrink it so far. I stood outside with the hairdryer for a very long time and finally had to pull off the plastic to pull it taut and then restick it. It worked, even when having to stick it down the second time on the same tape. That worried me but was not a problem. Just that darn cat.
