I tested z systems for over a month, and half z12, z2, z1,z7 they all lost MONEY. They all suck. This is not a system, this a scam. Stop scamming people telling them this system makes money SHAME ON YOU. DELETE THIS TRASH. I AM SURE YOU WILL GET SUED AT SOME POINT FOR FALSE ADVERTISING BECAUSE THIS IS SIMPLY FAKE AND BULLSHIT. I wrote this post because I couldn't find someone to warn me of this evil. you have been warned IT DOSNT WORK
