A major benefit (well...at least I saw it as a benefit) is the present as very unbiased to me. They do great research on the products they review, they are consistent, and they provide a clean, digestible "rating" on the devices they review.
I know they have to charge because they are not in any particular manufactures back pocket but $120 (annually) for reviews I use two times a year, if that, is a bit pricey.
I do wish them luck and I will sub when I want their opinion on a TV.
