I used to use it some years back when I was still on Windows and using Chrome. It was pretty good for a Windows environment. For a Linux/Mac environment, it doesn't come close to a proper terminal emulator. It'll do the job, but I recall there were a few things that were annoying.
I made it through my first semester of computer science using Secure Shell on a cheap Chromebook and a linux box back in my apartment.
Used this as my daily driver for dev work for years, works great. Only downside is it doesn't do emoji rendering well
