At first, this was a great service for topping up various platforms where well-known payment systems don't work. They charged a fee for their services, but overall it was beneficial to use. The main thing was that the service turned out to be reliable: there was never a situation where a transfer didn't arrive, money disappeared, or an extra fee was charged. Everything was transparent and honest. However, later they removed some features – canceled the purchase and activation of vouchers (which was very convenient), closed money transfers between users, and stopped currency exchange on the site. After that, I stopped using them, as I often needed these features, and found a similar service (though it's a bit more expensive, it offers the options I need).
