Look machine mart are just resellers, they buy cheap from China like all resellers do, even Clarke resell stuff produced in China,
If you want to take it back machine mart will likely be better than an EBay seller,
Machine mart don’t sell quality stuff, they used to sell cheaply made reasonable stuff, but cheaply made is so much lower quality and cheaper nowerdays, and they sell it as well,
If you want to buy cheap, do it, it’s your risk, come on here every year and tell us what a bargain it was, all smug like, with your super reliable 3 in 1 fantastic machine, and how wrong we are, we can’t tell you how reliable it will be, because we don’t have crystal balls,
All we do know is that in general it’s much more likely to fail, than a better quality machine.
Yes, I know all that about Machine Mart etc, the point I'm making is that such machines they sell can be OK/do jobs that us DIY/hobbyist folk want to do.
I totally accept that they may not be up to professional use,.....forgive me if I am wrong here but it sounds like you have a 'chip on your shoulder' against such machines.
