Example Input: Just "assembled" the bat cave for my 5 year old. Pathetic construction and workmanship -- half of the gimmics don't work. Another pile of injection-molded plastic parts and stickers that I get to assemble -- what is this thing -- $4 of raw materials + $2 of shipping + $10 of marketing? Garbage. Shame on you Mattel, the only thing worse is the batman figures with the batarangs that take 30 minutes and a blowtorch to get out of the packaging. This batcave will collapse and die within hours of play, I'm sure of it. GARBAGE!
Example Output: Negative

Example Input: I was installing these chips in a G4 Sawtooth macintosh computer and the chips did not work. I had kernel panics that eventually left the operating system unusable. The hard drive had to be reformatted and the OS re-installed. A great headache and PITA. I need to return these memory modules, how would I do that.best regards,vilppu
