Lifetime access isn't lifetime acces.
See mail of Certkingdom
Dear member,
Your Certkingdom Unlimited Access Pack is expired, the membership is valid for 3 years,
Reason- the lifespan certification is valid for 3 years after that you need to renew your certification.
Link to terms & conditions with 1 small item:
(a)After purchasing Unlimited Life Time Membership unlimited membership you will have access to all exam and training tools available at certkingdom.com. 3 years from the date of purchase
------------------------------------------------------------
So, you pay a lot of money and you cannot use it life time but 3 years. If you look at there website then they advertise with Lifetime Long.
I feel misled. My advise, don't buy the membership.
