Popped it off my keyring during a work trip and had my phone on the hotel TV in about ten seconds flat. The detachable clip is sturdier than it looks, and the 4K at 60Hz stayed crisp the whole movie. For something this small, it’s become a permanent part of my travel kit.

The 4K at 60Hz output is genuinely smooth—no stutter even when I’m mirroring fast-paced gameplay. It’s so small I forget it’s clipped to my keys until I need it, and popping it open takes one hand. Honestly, this thing has replaced half my dongle drawer.

The detachable clip is genius—it’s been living on my keyring for two weeks and I’ve already used it at three different friends’ houses. Plugging in the HDMI and seeing my phone mirror at true 4K/60Hz with zero lag honestly felt like magic.
