The yearly and lifetime plans are much more reasonable, and while we would usually warn against purchasing a lifetime subscription to anything (the company could stop developing its product or could cease offering its service) – it is worth noting that EaseUS has been going for 17 years, meaning that this company is well established and generally appears likely to stick around.
(If you do accidentally pay for two months you will literally have forked out just $10 less than it costs to use the software for the rest of your life which is obviously a very bad situation to end up in!) Just remember to cancel your subscription before the month ends, or you will end up being charged for another month at a substantial cost.
