As I do not have a TV at home by choice, I can only comment on the effectiveness of this product when it comes to cleaning the computer. At $9.95 each, you'll receive about 15 white wipes, and a cloth to dry afterwards.
The way this product is packed ensures handy storage. I have had no problems using it on my laptop, and is just as great to use on my iPhone. This product definitely removes dirt and fingermarks from computers and iPhones. I use each wipe about once a week.
