It's not going to be Class A, but I assume you're not really bothered as long as it sounds good , and at least the bigger models don't use an unusual power valve type like some of the smaller ones.
I'm not sure about the build quality - from this pic online, it looks like a right mess...

- not because it's PCB built but because it's covered in glue/goop and there are visible bodges. Hopefully this is not a full production model, but it's poor even if it's a pre-production sample.

My friend has one and its fantastic. He does about 10 gigs a week and used it without fault for nearly 2 years. I know he still has it and uses it occasionally.
As an example Fender now use hot melt glue to secure the wires a long the edge of their PCBs in several amp, eg Princeton Reverb.
Alternative strategies are cable ties, looping the wires through a hole in the PCB, or twisting wires together. For what it's worth, we use all these strategies in our amps.
I'd probably bet that your amps don't feature resistors tacked together above the PCB and partly buried in the mess, either.
It may well be reliable like that, but I'd guess it will belong in the "amps that are a pain in the arse to work on" thread.

We like to call it "anti service glue".
Seems a common feature in Chinese-made goods.

In fact large axial caps can't be stuffed by machine, so have to put in by hand.
I like to cable tie the caps to the board in our builds, or use a modest amount of silicone in repairs.
The smaller Supro models are fine too. I've got the Supreme which is 25w through a 10" speaker and I gigged last Saturday with a loud drummer. Still worked well and I got good amp breakup as I was able to turn it up. No problem filling the room and its actually funny to look at the amp and think such a big sound is coming from it
arted playing the Supreme without of pedal and it’s been good
