Does the program Learning Spanish Like Crazy (LSLC) really work?

I really want to learn spanish. I thought about getting Rosetta Stone but it's a little too pricey for me. Does anyone know if "Learning Spanish Like Crazy" (Vol. 1 & 2) really works? I can't seem to find anything negative about it online when I google it! And hey I'm just being honest, that kinda worries me a little bit! Can something really be THAT good that there is ZERO complaints about it?? If you have used this program, please let me know what you think about it.
