Been using for years but you're dropping the ball by not offering Radmin for Android (both server & client). As an IT Support Professional, the need for an Android version is more than necessary in today's mobile environment. I'm actually surprised your team hasn't tackled that yet.

If your demographic includes IT professionals, and it does, then an Android version is a critical necessity for their efficiency.  Not to mention the revenue stream it will provide to you.

Just a suggestion from one of those professionals from that demographic.
