Main highlights
- This product is manufactured in China
- This product adds a great value
- Product is highly durable and very easy to use
- If you want to open your windows in the warmer months, you'll need to take it off. Otherwise, sunlight and normal stress can also make the tape fail eventually. For a good seal, it's probably best to re-apply them every year.
