When I need to go four pages deep into Google results to come to a site that isn't a turnkey/clone of the site I'm trying to get information about, I see snake-oil salespeople. The first 33 Google results were sites that tout this product glowingly, and with exactly the same presentation---often the exact same layout, and sometimes the exact same page with different meta-tags. All are owned by the same two or three companies.
In other words, xtendlife is using marketing techniques that will effectively filter out sites with opposing or neutral views. If their product is as good as they claim, why do they need to do this?
If you want to unbiased reviews, it helps to go to forums that don't deal specifically with one product and look for reviews by people who have more than 1 or 2 posts. I haven't found many glowing reviews of this company on unbiased forums.
If the company's products are so world-renowned, they shouldn't need to resort to this kind of marketing. The only reason they get a "Meh" from me is becuase it's possible that their products are okay. I wouldn't want to spend my money to find out, though.
