Review: Cheap but effective draft stopper - For the price, this does the trick to cut down on drafts coming from indoor/outdoor entryways. I applied this to both my front and back doors in my house where there’s always been a noticeable draft and it’s definitely helped to cut down on it! I do like that it’s white and blends in with the doors so it’s not super noticeable. Easy to install and stick on too just make sure to measure and cut it and good to go! This one order of the 2-pack was enough for me to do these two doors but if I decide to do my door to the garage next then I’ll need to order some more.
Review: heavy and durable barrier for any door - This is a great product. The plastic is heavy and durable. The adhesive hive strip makes it easy to line up perfectly. Heating the glue with a hair dryer a little then pressing it in again will secure a lasting barrier. Recommended for everyone who has a draft in their door!

## 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.
