I gave www.u-i-group.com a fair chance. After for a few weeks now of usage, I can say with confidence that there are far better options available. The interface is clunky, the fees are higher than competitors, and the customer support team seems overwhelmed or understaffed.
Pros: Fast deposits|Two-factor authentication|Good mobile app
Cons: Withdrawal takes 1-2 business days|Desktop app not available on Linux
