I got a vouch copy from @PainChocolat
I can say that he helped me to set up the bot and to find the token (he sent me a 1minute video that is quick easy to follow).
The tool works as described, he sent me an invalid nitro gift and the CLI (command-line interface), instantly said that the code wasn't valid, I do know that it works, now he told me where I can search for servers that give nitro links.
The bot works flawless, I don't know if they are more bots of this type in the market, but of course, it's faster than a human.
PD: The OP told me that it could be detected as a virus but I didn't have that problem.
PD2: For anyone that is planning to buy this, I recommend you to have it running 24/7 on an RDP
The program is simple and does its objective, so I cannot say bad things about it, it works fast and I got good support, I think that 5$ is not a bad price, but the key to grab nitros is to start joining lots of servers
