I bought the adapter so I could wirelessly push my video and sound to my big screen TV. Its normally $100.00 but got it to the door for $50.00. I use it all the
time. Works amazing well. If I'm using youtube or watching a video seeing it on
my bigscreen TV with sound is well worth the money. Its so easy to use, just turn your TV to the correct HDMI input then on your phone click on Allcast Share which is
in the dropdown menu now. Its worked perfectly ever time for me. Not sure if its a
good game playing solution but videos work fine and I stream all my music to my
TV using it.
