I kept getting tension headaches from staring at my phone every night. PortaPad's PortaPad completely fixed that. The screen looks so much bigger and my eyes feel totally relaxed now.

Threw it in my carry-on and used it on the flight and at the hotel. Sets up in literally five seconds. Zero complaints.

Honestly I thought this was a gimmick. It is not. The image is legitimately sharp and clear, and I have not watched anything on my phone without it since.
