DigitaLinxHDMI ADAPTER RING DL-AR1906

I was somewhat worried based upon a review of another product by this manufacturer that stated these were passive not active HDMI adapters, and that they didn't work for MacBooks. Well, I tested this product with all of the following devices, and it worked perfectly:Dell XPS 13 (L321X) - Mini Display PortDell XPS 13 (9350) - USB-C/ThunderboltDell Precision M4800 - Display PortMacBook Pro (Retina, 15-inch, Mid 2014) - Mini Display PortMacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) - USB-C/ThunderboltMacBook Pro (15-inch, 2019) - USB-C/ThunderboltMy testing was so successful, that I have been convinced to purchase another one of these for my other conference room.The only other suggestion I would have, to make this a perfect product, would be if they could add an HDMI (female) to Lightning (male) connector, so that iPads, iPhones and other tablets/phones could connect as well. And that it would be in black, to match the other adapters. However, they do sell an accessory to add Apple Lightning to Digital AV adapter onto the ring, (that ring adapter and Apple's dongle are white however, so it doesn't look as uniform).

everything is great except they give you screws with a funky tops and no tool to install them so the screws are useless.
