I bought Drainer. I’m pleasantly surprised that such a rare product is available at a relatively low price.
The tech support team ran tests, stayed in constant contact throughout the setup and testing process, and helped resolve any integration issues that came up.
As for the software, there are no wallet alerts, but it has a must-have feature in the form of auto-debit (something that’s missing in MaaS projects).
It’s a game-changer, since it makes it much easier to get that coveted approval from the big players.
I definitely recommend both the tech support (as a person and a professional) and the product itself.
