Some information.

there are some vendors who will not say a bad word about a product they sell unless they quit selling it. Then the truth may come out.

Keep that in mind when weighing user versus seller responses.

Now if a vendor was willing to back up their faith in the product by agreeing, in writing and in advance, to a 100% refund all costs to you if the product turns out to be a POS, then yeah give it a shot. And that's ALL costs, not just a refund of your purchase price.

Let us know if that unicorn shows up.
