Zoolz sold me two lifetime plans for two computers for backup purposes a little over a year ago. About six months into the lifetime plan I was told I needed to pay "maintenance" in addition to the upfront subscription. Then today, all users of lifetime plans were cancelled and given two weeks to download their content before it was deleted. Zoolz scammed a lot of people. (I wouldn't have been shocked if it was several years - but come on 14 months? User's recommendation: Do not buy from this company.
