Review: Bonne qualité et efficacité. - Très facile à installer et as une belle allure et fait très bien le travail pour couper le froid.
Review: works great and is EASY to install. - just got it and installed on one door in around 5 minutes. not difficult at all. fits perfect and stops cold air like it should. if i see longevity issues, i'll update if needed. for now, this is a great product and a good value at the current price (when getting the 40ft roll). i have plenty left to do my front door.......and after that there'll still be enough left over to replace both doors again in the future (if needed). very satisfied.

### ⭐ Seals gaps of 6mm not up to 13mm as claimed
*by L***Z on 15 May 2026*

Bought as it states that it can seal up to 13mm gap. That would be ideal for me. In reality it can nearly do 6mm. Unfortunately I've already cut it. Waste of money and long delivery time.
