GL.iNet Comet Q (GL-RMQ1) is a palm-sized remote Keyboard, Video, Mouse (KVM) switch. It plugs into a phone, tablet, Mac mini, or laptop via a single built-in USB-C cable and gives you full control of that device from the GL.iNet GLKVM app or browser, with nothing installed on the target device itself.
I backed it on Kickstarter at the Early Bird tier, US$79 (~S$100) with US$10 (~S$13) shipping to Singapore, so US$89 (~S$113) all in. It shipped on 24th August 2026, and I received it on 31st August 2026.
The campaign hit its US$10,000 goal within two minutes and closed on 2nd July 2026 with 6,741 backers pledging US$1,155,193. It now sells on the official GL.iNet store at US$139.99 (~S$177), currently sold out. There is a GL.iNet official store on Shopee, but Comet Q is not listed there yet.

Design
Comet Q is round, weighs 78.5g, and has a 1.8″ touchscreen in front. All the configurations can be done using the screen.
The captive cable carries video, data, and power in one go.
And a second USB-C port takes external power if the target needs charging while connected.
It comes with an orange silicone cover that protects the edges and has cutouts over the Comet Q’s ventilation holes.
Video comes in over DisplayPort Alternate Mode (DP Alt Mode), a way of sending display output through a USB-C port, at up to 2K QHD at 60fps over Wi-Fi 6.
Check this before buying, because plenty of USB-C ports are data-only or power-only, including on some mini-PCs.
If you want to use the Comet Q on iPhone, DP Alt Mode is supported on iPhone 15 and newer, but not the iPhone Air, 16e, or 17e. Do not go by USB speed either, as the iPhone 16 Plus is USB 2 and still does DisplayPort. If you are unsure, check Apple’s tech specs for the term “DisplayPort” under the connector.
Setup
Plug it in, and your Mac asks how to output to it. Pick Mirror the Entire Screen and tick Set as Default.
Set the orientation on Comet Q itself, since your USB-C port could face any direction.
Then join Wi-Fi using the on-screen keyboard.
The the on-screen keyboard, which is surprisingly easy to type on for something this small.
Local access works immediately. For remote, generate a binding code on the screen and key it into your GL.iNet account through the GLKVM app.
Despite choosing Entire Screen, my Mac registered Comet Q as an Extended Display, so none of my windows appeared on the remote feed. Switching it to Mirror manually in Display settings fixed it, and it stayed that way after that.
Usage
Local connections on the same network are responsive enough. Remote over the internet lags, which is expected. Not a deal breaker. GL.iNet lists two-way audio, so you can hear the target device and talk back through it, though I have not had a reason to use it yet.
If you are worried about privacy, you can also route it through Tailscale or < a href= "https://zerotier.com"> ZeroTier instead of GL.iNet’s cloud relay, and GL.iNet’s documentation says neither requires the GLKVM app or the cloud service at all.
I have no use case for remote controlling my iOS devices, so I will be using it for my M5 Pro Mac mini when it arrives at the end of September 2026.
Regardless, before buying the Comet Q, ensure that the device you plan to control remotely supports DP Alt Mode.
