Review: Easy and effective - This is my first winter having it in place and there is a very clear difference in the temperature on the bottom floor of my town home as opposed to last year - finally the heat is staying in! The product was very easy to apply (I am a bumbler when it comes to home repair and I had zero difficulty) and looks much better affixed to my front door than the previous gap that had caused me so much issue. If you’re searching for something to help cover that door gap, this is perfect.
Review: Easy to Apply and Install on Doors - These are very effective for reducing draft under doors - especially the front or back door of a house. I recommend laying them flat a couple of days so that when you attach to them to the door, they stay level and flat and seal draft from underneath the door. Overall, very noticeable improvement.

## Questions & Answers

**Q: can I double one on top of the other to cover a larger gap? If not, please rec a product that covers a 2" gap. Thanks!**
A: No, that won’t work, I tried! Order this instead. It’s more expensive but super thick and sticky, comes with brads as well and closed over a 2” gap on my screen door. Yahhh …no more critters can get in! I’m ordering another set today to do both sides of the storm door.

**Q: Can it come off easily without ruining door?**
A: Yes, mine did. You may need to apply a blow dryer to heat it up some. But it comes off.

**Q: Will this damage a painted door or wood door upon removal?**
A: Yes, it destroye the paint on my bedroom door don't do it!

**Q: Does this work better when placed inside or outside the door?**
A: If it is an interior door like a bedroom door, you can put it on either side.  If it is a main door leading to the outside, I recommend using it on the inside.  You can put it on the outside but weather conditions will deteriorate the quality of the product over time.
