I too was ready to buy this product, but will not do it if I can't get the color I choose. I guess this company doesn't want to put their customers first!

Ex Output:
Negative

Ex Input:
overall, the documentary was pretty cool. however, about 99% of the beach boys clips were from a prior documentary, an american family from '85. they should have included the clip of dennis singing manson's song never learnt not to love (aka cease to exist). especially since the title of the movie is the beach boys & the satan. but did have cool footage of interviews with dick dale and dean torrence and the chantays. also kim fowley was cool too.

Ex Output:
Positive

Ex Input:
I bought it before I knew anything. Now that I have been training a bit more and reading more I realized that this book is lacking a whole lot. I do not really recomend this book unless you can get it for free.

Ex Output:
Negative
