Cheap solid state relays

I knew these knock off solid state relays were under rated current wise but the common 40 amp models have a triac inside rated for only 16 amps!

It lasted a few years doing intermittent duty in my coffee roaster before shorting closed. There doesn't seem to be a middle of the road price point on these. Legit models are like $40 and fakes are $6.
