Psilan:

 

My Shields have been going well. I just used a travel adaptor to sort out the pro.

 

The pro or the tube isn't as snappy around the menus as my TV, but obviously the playback destroys it. I don't play anything high bitrate on the tube.

 

the shield pro menus are slower than your tv? in the plex app too? what model tv is it? that is pretty suprising
