Review: No tools to install, floats to fit - Unlike other door sweeps, this slides on with no screws or other installation required. A good tight fit to the floor, and you can trim it easily to fit the width of your door. My apartment door had holes and even broken screws (sticking out about 2mm) from a previous door sweep. This one slid over it all tightly with a little help. White is pure white, not cream or bone colored. Sweep hugs the floor: will push any area rug out of the way when you open the door. Concerns: 1) a part of mine also wore off and broke away, as seen in other pictures. But the seal is still very tight. 2) if you have a faux wood laminate floor, with a slight texture to it, the soft foam part of this seal will squeak against that ridged surface when shutting your door, much like a violin bow across the strings.
Review: Pretty happy about that - Overall it worked well for me, it reduced the draft under the door about 90-95%. Pretty happy about that! I needed this door draft stopper for my back exterior door. It worked well because the track width was wide and deep enough to grab on the bottom of the door and stay in place. The top of both sides of the track were high enough to fit nice and snug to the door. The only problem I faced was that it was a bit longer than my door and when I tried to close the door a bit too forcefully, I cracked the stopper at one edge. But that was my fault... lucky the crack was fairly small and I fixed it by cutting the stopper on one side to fit the size of my actual door. It seems to be hard and durable enough to do the job, but flexible enough to be cut and adjusted to size. I can see how some people would say that is flimsy... but is not that flimsy is just flexible to fit on different doors with different sizes. My door is pretty thick and I was worried it wouldn’t fit. I am glad it did. But I can see how a smaller thinner door would not work well with this stopper. However, I added a few screws through the door stopper and the door. Now is tightly and snuggly secured and I won’t be able to move it no matter what. Make sure you measure your door, but it works well with my door. I hope the pics and the review helped. It also came in a good packaging well protected and on time. I didnt give it 5 stars because all and all, it is made of a lighter material than I would like...

### ⭐⭐⭐⭐⭐ Effective and Easy to Install
*by J***. on January 16, 2024*

I recently purchased the Slide-On Door Weatherstripping and I am incredibly impressed with its performance. Living in a colder climate, I was constantly battling drafts and struggling to keep my home warm. This weatherstripping has been a game-changer. The installation was a breeze as it can be easily cut to fit most doors, making it versatile and adaptable. Once installed, I immediately noticed a significant difference in the insulation of my home. It effectively prevents drafts and keeps the cold air out, providing a much more comfortable living environment. The slide-on design is convenient and ensures a snug fit, without the need for any adhesive or additional tools. I appreciate the simplicity of the product, as well as its effectiveness.
