YESUS Wallpaper Frame Rolls Differed Noticeably in Stickiness

I was looking for an inexpensive way to refresh the look of my 2 bathrooms. Found this item, read reviews, and viewed the videos, and decided to purchase one roll. I measured to make sure one role would be enough and I thought it would be. Easy enough to apply at first. I appreciated the first role I purchased came with a backing with lines which made it easy to cut the length and width I needed. I used a pair of scissors to cut the strips I needed and a sharp exacto knife for finishing trims to adjoining sides and edges. I completed the first mirror but found I was short of material for the second mirror so I purchased a second role. The second role was vastly different quality than the first. The backing did not come with lines and the stickiness was waaaay more sticky. The stickiness made cutting and the application of the strips once cut a real pain. It took me twice as long to do the second mirror as the first and although the second mirror is a larger mirror it isn't that much larger. Plus I had gotten my feet wet with the first mirror so built up some proficiency and confidence in my abilities so it shouldn't have taken twice as long to get the second mirror done. But it did. The stickiness of the second role was so sticky I wouldn't even describe it as "removable". When making corrections to alignment while applying the border to the second mirror it was very difficult to handle and tore easily which didn't happen with the first role. The stickiness of the second role is also quite concerning to me because it feels like this product won't be easy to remove once I decide to remove it for a different look should the time come for that. In fact, I had to use acetone to remove the sticky substance that was left behind on the mirror in those parts I trimmed finishing touches. The pictures I've included should be viewed as such: Where marked "1" and "2", 1 = the second role I purchased; 2 = the first role I purchased (yes I understand this is backwards but it is how I marked the pictures so .....) Because the second role was so difficult to cut cleanly I got jagged spots which you can see in the close up picture. Not terrible but annoying, you can't see it from a distance. I gave this product two stars primarily because of the inconsistencies between the first and second role purchased and the issues these inconsistencies actually caused me. Needs better quality control. Overall not unhappy with the outcome but disappointed with certain aspects of my experience.
