This is an interesting service.
Are you leaving a real review based on the product or just leaving blind reviews?
Please read the OP again. I'm doing this service keeping in mind with what customers might doubt before purchasing the service. Obviously, I will post an in-depth review after reading/testing it fully. So there's no scope for blind/biased reviews.
Lastly, it's gonna be free
forever.

If this is the case then you deserve positive rating for work done by you (as far as you do not cheat anyone in anyway in this forum) .
