All the provided domains are high quality, they will not die, block or hold; they can last forever and can be renewed easily by me.
Warranty is given as the time you buy the domain name, if you buy it for X years then the warranty will last for X years.
Is it possible to transfer the domain to the buyer's account? "easily renewed by you" but who knows where you will be after one or two years? I never recommend to anyone when buying a domain that he is not under his control.
.com registration on domains.google cost $12. Whether it is safe legal your registration method? here is already reselling domains using a stolen credit card for payments. I don't have to tell you that all domains have been taken away by the registrar.
