I found it great for traveling. I’m our car (Sienna) we wanted to watch Netflix and other streaming services. One could purchase a dongle and hotspot the dongle to cell phone and this would also work for hotel TVs with HDMI input. I know some cars have another cell plan but this eliminates the need to pay for those if your car has HDMI and gives you more streaming service options since it mirrors your screens.

I always found the USB sticks and hotspot a nuisance This adaptor let’s you output the phone or tablet to HDMI to any source.
