It's listed as a Floureon 2l heated one, but when it came it's badged as GT Sonic, it is quite a solid piece of kit, all stainless steel, it makes a mess of a piece of tinfoil which seems to be the standard effectiveness test. It's a chinese seller, but Amazon gives guarantees about returns from 3rd party sellers and it was despatched from a uk warehouse, and when I emailed them they replied in legible english, so it's been hassle free for me so far.
I have the same one and I still get the white marks , I mainly use mine as a hot water tank with the solution and a toothbrush now
