Stealth Ultra controller questions.

Quick question to those with the stealth ultra controller. Can I connect this directly to my pc via Bluetooth without the dongle? I know it won't be as responsive as using the dongle but is it possible to just use Bluetooth like a regular xbox controller? Having to use a dongle is a deal breaker for me for a few different reasons. Just wanted to know? I keep seeing different answers. Any info would be appreciated!
