Just got the Darbee, I don't mine the Darbee logo at the bottom of my projector when I'm changing the % but I don't like it appearing forever on the screen even when I turn it off. It's like Samsung alway appearing on a Samsung TV.
Also note that you can go into the menu and turn off all of the lights on the DArbee. I was pleasantly surprised when I found this feature. Thought that I was going to have to tape the unit up to hide the bright lights.
