Still no response from him after I sent my details, kinda worries now...please don't let me post negative about this, actually im doing it
this post to be edited depends on OP action.

EDITED:
I received the vouch and here is my review. Yes it works it upgrade my existing account to premium(yes you heard it my own account) means less disturbance as there is no chance the account will stop because the real owner change the password. OP will add you as part of family premium plan. The only disadvantage are you don't know how long this account will last but if you trust the OP enough maybe you can risk your $6 for his lifetime warranty offer. just contact him once your account back to free version...I will monitor this offer and let everyone once my account back to free or not been replace. PM me if you want updates about my account status.
