GTMEDIA HDTV Mate ATSC 3.0 Tuner Stick vs ADTH NextGen TV Box Gen 2

Buy the ADTH NextGen TV Box Gen 2 if you want to watch on a regular TV: it outputs up to 4K HDR with Dolby Digital Plus and AC-4 audio, has a built-in DVR with 64GB of storage, and works without internet for unconnected DRM channels. Buy the GTMEDIA HDTV Mate if you watch on an Android phone, tablet or TV box and want a small USB stick that needs no HDMI cable. The ADTH is the more capable living-room device on paper, but its 2-out-of-5 rating from owners is a real warning sign, while the GTMEDIA's 4.7 from 17 ratings is a small but positive sample. The GTMEDIA caps output at 720p and needs the HDTVPlayer app plus Android 9.0 or newer, so it is not a TV replacement.

• Choose the GTMEDIA HDTV Mate if you want free over-the-air ATSC 3.0 channels on an Android phone, tablet, projector or TV box through a single USB port.
• Choose the ADTH NextGen TV Box Gen 2 if you want a set-top box for a TV or monitor with HDMI, 4K HDR output, surround audio and built-in DVR recording.
