Real stainless
Is there any reference that would say if it is real stainless steel (non-magnetic) which makes a big difference?
Magnets can stick to some stainless steel, depending on how it was made. Most stainless steel in appliances will not hold a magnet, but this characteristic alone doesn't determine whether or not the appliance is made of stainless steel.
Specifically, ferritic stainless steel is magnetic, while austenitic stainless steel is not.
