If the minimum threshold of 10,000 rubles doesn't bother you, then this exchange service has no drawbacks. I am very satisfied with their services, I often exchange currency, and the waiting time for the transfer in the desired direction never exceeds 10 minutes. The reserves are large. The rates for YuMoney and Qiwi (which I use most often) are excellent. I always compare the rates with the best offers on BestChange — the difference is reasonable, fluctuating within 2-5%.
