Just seen these Demonfx pedal clones on Aliexpress.
Looks like they've got potential, especially at the typical Chinese clone low prices.
And even if they sound bad, you get an enclosure, knobs, sockets, footswitch, etc.
I can't see any demos on YT, apart from the green Tube Screamer, so they might be quite new.
Here's the webpage
