Easy to use
It works well. I was surprised by it's flexibility and its ability to stick into tight corners. It's nice and thick, so it seals up well. It has a smooth, semi-gloss texture and transparent, so it doesn't stand out. It feels almost rubbery. I used it for the output panel from a portable AC, and didn't need to use a whole lot, so I expect the roll to last a long time.I'll update if something goes really wrong, but so far I am glad that I bought it

Very effective way to save a lot on heating costs for only a couple bucks
Our apartment has really crappy windows, they're those metal ones that don't even seal when they close, you can always feel a draft coming from under them, there's 8 windows in our apartment like this, and our heating costs were threw the roof this winter. Obviously, this is because the heater has to run nonstop because all the heat escapes out the windows so we never get the apartment to a comfortable zone. If this sounds familiar, GET THIS PRODUCT! We needed two 30YD rolls for our windows, but it is super easy to use, same as just taping up anything, you can re-adjust the tape while putting it on as it's really stretchy and has a super strong adhesive, once it's on it stays on, it's a nice thickness, and after taping up 4 of the windows in a corner of our living room, the drafts were gone!! We can walk near our windows now without getting colder, and that's a massive improvement. Even now the last few days the apartment actually heats up in the sun now and retains the heat, instead of ALWAYS being freezing unless the heats on. Save yourself potentially a lot of money on heating and buy this cheap, quick and effect product!

Wish I found this years ago.
If you have a portable air conditioner or drafty windows: this is your go to short term solution. I got this stripping after buying a portable air conditioning unit for an apartment. I used it to place around the intake and exhaust hosing the attaches to the window unit. There were spaces where the hose attached to the window unit and I covered the spaces with this strips which helps with my electric bills. I also used it for a window screen that did fit snuggly and had a got which allowed bug to enter through the gap. I place a strip on the outside over the gap, no more bugs and the tape stayed in place the two years I lived in the apartment. I recommend this tape because it has never failed me. It sticks without loosing its grip as long as the surface is clean of dirt and debris and the surface is dry. I recommend this tape.

great protection
This has great wind protection, for in-between crevices in old windows. It also bends well around corners, etc. Just not sure if it will take off any paint, because it is extremely adhesive. It does come off for a second, if you want to fix it, while laying it down, in other words, it's workable. I recommend it.

It’s sticky
Quality tape.

Effective and easy
This worked very well. My window had gaps due to a current construction project, which was making the room uncomfortable. This helped tremendously. I only need it for a few months so this was a good solution.

works, but be aware for removal.
Works....BUT mess if you need to remove. This works as intended on a couple of our old windows for winter. BUT, come spring this has been a MESS to remove.....left windows sticky....we have spent DAYS of cleaning off....with Mineral Spirits, Nail polish remover, Goop Off - you name it. We open our windows in good weaher...so we will NEVER use again. We are still finding sticky spots. Not worth it......Use heavy curtains is best unless you are one to never open your windows for fresh air.

Skeptic converted in 24 hours.
I live on a busy street and the traffic noise coming through my front windows was really getting to me. Bought this tape mostly skeptical, figured it'd help a little but probably not much.Wrong. Put it on two windows and could tell the difference the same day. Like, immediately. That's actually why I'm writing this only two days after getting it — I don't usually bother reviewing something that fast but it genuinely surprised me.Application was dead simple. Sticks right away, no fighting with it, no peeling edges. And once it's up it's barely noticable — had to look twice to remind myself I'd even put something there.Only been a couple days so I can't say how it holds up long term, but so far it's doing exactly what I needed it to do. For a busy street house this thing is worth trying.

Isolation de qualité
excellent vraiment. Si les mousses ne suffisent pas pour isoler une fenêtre, cette bande semble l'ultime recours.Colle étonnement bien sur bois, plastique, pierre. Plus grand chose ne passe pour l'instant.Faut voir si cela tient comme cela pendant des semaines,alors je peux qualifier cela de produit miracle pour isoler , couper net les courants d'air.Pas trop cher, en plus

Solución eficaz y discreta para eliminar corrientes de aire en ventanas
Compré esta cinta adhesiva aislante transparente porque por el marco de una de las ventanas del salón entraban muchas corrientes de aire, debido a la mala calidad del cerramiento y a la falta de puente térmico. En invierno se notaba bastante y hacía que la calefacción se encendiera con más frecuencia.Tras comparar varias opciones, me decidí por esta cinta porque ofrece más metros y mayor ancho que otras marcas por un precio más ajustado, algo importante si tienes varias ventanas o marcos que sellar.La colocación es muy sencilla. El adhesivo es fuerte, pero durante la instalación permite despegar y recolocar ligeramente si te equivocas, lo que ayuda a dejarla bien alineada sin estropearla. Una vez colocada correctamente, queda bien fijada.Después de varias semanas de uso, las corrientes de aire han desaparecido. El cambio se nota claramente en el confort del salón y también en que la calefacción entra menos tiempo, algo que se agradece en el día a día.En cuanto a la resistencia, ha habido días de mucho frío con condensación en la ventana, y la cinta no se ha despegado ni lo más mínimo, ni siquiera al pasar una bayeta para secar el agua. En ese aspecto, muy buen resultado.El material tiene buen grosor y, al ser transparente, apenas se nota visualmente una vez colocada, incluso sobre marcos claros, lo cual es un punto muy positivo.En resumen, es una solución sencilla, económica y eficaz para mejorar el aislamiento de ventanas sin obras. Muy contento con la compra.

Great product but leaves a lot of residue
If you don't mind cleaning over where the tape was for 1 hour after removing the tape this is fine. I don't know why but a heavy residue was left and incredibly difficult to clean. This is definitely not why we bought this product. I'm not sure if there are many limitations on how long you can leave the product on for?
User
Great product, does a great job!!!
Excellent!!I have many drafty windows in my house and used this , along with our very cold Alberta winters, this product amazing stopped the drafting on all my windows!!I even put a layer around my fireplace!!I don’t use it anymore so no risk of a fire, nor does it stick to brick very well,, but it works good enough for me, at least I will get some protection for my wood burning fireplace, as the drafting on the fireplace is quite strong,, it works great, and I’m very satisfied!!!!

Strong tape
Strong tape, easy to mount. After the removal I used anti glue material to remove glue leftovers from the window fence.
