Bad experience, there's no way to find your Roblox ID and that's what it takes to redeem robux. They also keep adding Zeros to the gems (you need those to redeem robux) I tried typing a random code so that way I know someone out there gets the robux because I went through a long time to get the gems for the money and it says watch over 50 ads so we know your not a robot. Sorry but I'm not gonna watch 51 ads to give robux to a random player.So you can go for it but I don't think it's worth it.
