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.
Review: Perfect - Works perfectly. We'll worth the price. Seems very durable. Easy to install. Insulated my door. Now no drafts and cut down on the noise. Easy to cut to size.

### ⭐⭐⭐⭐⭐ Seems to be very good replacement.
*by A***R on May 3, 2026*

This product was a perfect replacement for my old double 8ft front doors. Easily installed in minutes. Just measure your old weather strips length or measure the frame. This particular stripping fits in a 1/8" slot on your frame. I was able to buy it in Black , some companies don't sell it. Made a big difference in sealing my door. I think this seems of good quality and I'm very pleased. I going to buy some more for my other doors.
