Review: A great brand to use! - Weren’t sure about this as it wasn’t a brand I would normally get, but we no longer feel cold air coming in through our windows, I would get again for sure! Easy to put up, quality is great, value, functionality all great!

### ⭐⭐⭐⭐⭐ Helps Warm the House
*by B***A on December 23, 2025*

Very inexpensive way to help warm the house. The films really make a difference! It is a bit challenging to peel the tape, though. I found ripping it a little helps.

### ⭐⭐⭐⭐⭐ A great brand to use!
*by J***A on January 15, 2026*

Weren’t sure about this as it wasn’t a brand I would normally get, but we no longer feel cold air coming in through our windows, I would get again for sure! Easy to put up, quality is great, value, functionality all great!

### ⭐⭐⭐⭐ The wax paper back adhesive
*by A***I on December 21, 2025*

I would have gave this product 5 stars but the stick adhesive is such an issue, getting the wax white paper off to separate it. Very frustrating. Other than that it’s a good product for leaky windows in the winter. I use it every year. Until I decide to get a few new windows in my home.
