Bests & Worsts Reviews from Amazon

I ordered this stuff based on all the rave reviews on Amazon. After I got the product, I understand... These guys tell you that if you post a review on Amazon, they'll send you a free product, up to a $35 value. They do ask for an honest review, however, you have to call them and let them know your order number with Amazon. If I weren't so pi**ed off by this, I probably would have given them 5 starts too, because I don't feel right dissing a product and then ask for a free $35 gift! Wow! Is this ethical? Amazon? What's your take on this? As per the product itself, I'm comparing the omega levels to Twinlab complete EFA pills that I already had at home (Nutrigold also has of course Phospholipids and Antioxidants which are not found in Twinlab): Per pill: Omega 3: Twinlab - 424 mg, Nutrigold - 300 mg Omega 6: Twinlab - 309 mg, Nutrigold - 12 mg Omega 9: Twinlab - 158 mg, Nutrigold - 65 mg So looking only at the omegas levels, seems to me Twinlab wins. BTW, Twinlab suggests taking 3 pills a day, whereas Nutrigold suggests taking only 1 pill. Meaning for example, Twinlab suggests you take 1272 mg of omega3 a day, and Nutrigold suggests taking only 300 mg. Very confusing. I didn't bother to research this after I saw so many 5 and 4 stars reviews of Nutrigold. All in all, I don't know if this is a good product. As I said, I didn't even research or compared products once I saw the tons of perfect reviews this product got. Now that I know that they offer gifts if you leave them feedback, I kinda feel cheated. I really don't like this marketing method, and I would encourage Amazon to look into this and see if they think it's ethical.
