Great exchange service, I don't understand why there are so few reviews about it. It is really very popular — according to my acquaintances who actively use it and recommended it to me. It always offers a good rate and has large reserves. The exchange happens automatically and almost instantly. I have used it many times — I consistently exchange 3-4 times a month and am completely satisfied. I can't say anything about the support service — I haven't needed to contact them. Overall, I recommend it.
