Query: Waste of money

I purchased this to calibrate my new $4,000 Samsung TV and was very surprised at how useless it was. The instructions were somewhat vague, but my main problem is how little the product did for me. It shows a test on the screen and asks you to use your own judgement or opinion as to what looks best, as in there are no finite instructions. I could put a regular movie on and set these same settings based on my own judgement and opinion of what looks best.In the end I made few adjustments, and certainly none that I couldn't have made without this product. Don't waste your money, just put in a movie and tweak settings until it looks the way you prefer.
