I have brought from them before and they usually guarantee what you want, but with games like Wuthering waves and genshin it is risky. I brought an account, only for it to say there was an ‘error with the account or password’ so, I emailed them. It’s been 2 days no response. Luckily I did rebuy it and the account finally worked, I got R2 Phoebe which was more than what I had expected, but no sane person would rebuy an account after the first one fails, esp $24 which is roughly £18. So just remember nothing is guaranteed to work out, but 95% of the time they do work.
