    • Firmware update is a must
Color: orange
Works great after firmware update. If you are on iOS it’s going to be required for it to work most likely. Press the button on the adapter 3 times while powered on via USB and plugged into the HDMI on the TV. Join the SSID (wifi name) it is broadcasting as shown on the TV. The password will be listed. Navigate to the IP address in your browser (treat it like a website) and set up the adapter to connect to your home WiFi. This will trigger the firmware update. It’ll now work with all your devices (Android, iOS, MacOS, Windows) as of 4/11/26. The update greatly improves the experience. It easy to use now, decent price, and versatile. ... show more

Amazing streaming and mirroring option. So this has two modes, streaming/casting and screen mirroring. I only bought it because I needed a mirroring option via Airplay and Android/PC (miracast) without needing to be connected to the network which is very hard to find devices that are standalone like this. You basically just select the w3403, input the PIN on the screen and go. The latency is very minimal, even better than my AppleTV 4k. I’m very impressed. No audio or video out of sync and it just worked. You will need to plug in a usbc cable but I just used one off my TV. Easy peasy up to 4k mirroring. ... show more

    • Did not work with windows.
Color: orange
It did not work for any of my windows computers (tried 2). One of the computers I use all the time to wirelessly (via Miracast) connect to external monitors using other dongles. Unfortunately, this dongle would not do the trick. It worked with Android, but not windows. External monitor screen went blank after connection and no amount of display settings, dongle button pushings, etc, made it work. No error message. ... show more

    • Easy to use and works great
Color: white
Honestly, this little Tongtion dongle is amazing! It's pure plug-and-play—no apps or Wi-Fi settings to mess with. You just press the button and your screen is on the TV. The connection has been solid. It's tiny and portable, easy-to-use option for home and travel.
