I think certain people need to remember the phrase "caveat emptor" - buyer beware. There's no guarantee that anything you purchase is going to be to your liking. You have to accept the risk that you could be wasting your money. Because unless the product is physically defective in some way and the producing company is responsible, the rest is on you. You paid the money, you accepted the risk.

If the end product is not to your liking then give the company constructive, polite feedback so they will have a better idea of what their users like and dislike. You're more likely to get a better response that way and to have your comments considered for future products.

But that's just my 2 cents on this issue.
