AntCloud review: Can it really handle 4K gaming at 60 FPS?

I recently subscribed to GeForce NOW Ultimate, as I can't afford a gaming laptop right now due to the recent price hikes. However, some games I want to play aren't available on GFN.

I'm considering AntCloud as an alternative. Has anyone here used it recently? How's the performance and stability, and can it actually handle 4K gaming at 60 FPS?

Would appreciate some honest user reviews or alternatives.
