## Customer Reviews

### ⭐⭐⭐⭐⭐ Great door draft stopper for indoor and outdoor use
*by G***Z on June 1, 2025*

I bought the Grotheory 2-Pack Door Draft Stoppers to block drafts, noise, and dust under my doors, and they work exactly as expected.Pros:Easy to install and fits most standard doorsEffectively blocks cold air, dust, and noise from coming inDurable material that holds up well over timeClean white color matches nicely with doorsCons:Might be a bit wide for very narrow door gaps, but usually no problemOverall, these door draft stoppers are an affordable and practical way to keep your home cozy and quieter. Definitely recommend!

### ⭐⭐⭐⭐⭐ The best!
*by I***P on June 25, 2025*

This is great! Keeps the cold air (AC in summer!) in the room by blocking the gap AND the adhesive grips SO well. I also noticed that the sound of the tv in the room is not as loud outside of the room so that is a bonus. I got it and put it right on. The instructions are clear and easy. I’ve tried other gap blocker strips and this is by far the easiest to install and works the best!

### ⭐⭐⭐⭐ Great for blocking light and reducing noise!
*by C***� on July 3, 2025*

We got this door stopper to help seal the gap between the door and the frame. There was a lot of light coming through, and we also get a ton of bird noise early in the morning from a tree outside our house. This product really helped! It completely blocks the light — not a sliver gets through. As for the noise, it doesn’t block it entirely, but I’d say it cuts it down by about 60–70%, which makes a big difference. Easy to install and does the job!
