This is my review for Monster Multi-USB LED Light Strip - 6.5ft. Now opening the box, the instructions are quite simple. Clean the area where you are going to apply the light strip. The strip comes on a small wheel so you can use that for the application. I did not. I have a 65" screen so I wanted to see the whole strip for better placement. With this length I was able to go across the top of the TV and about 6" down each side. 
Now it is somewhat difficult to pull the backing off without pulling of the adhesive. I pulled off about 2 feet of the adhesive before I had even realized I had done so. I was gentle but just be aware and press the strip firmly before you start pulling the backing off.
I was concerned it might not look good on a larger TV but it did! I am really happy with the product. I would add that if it had more colors it would be even better.
