How can you be sure [1] is fake? To me the picture looks like the real one reported in [2].
Read the UL warning notice. Note that the real ones have a bevel in the plastic frame outlining the product label,
(this prevents putting the label in upside down) while the fake ones do not, even though some have a corner cut on the label. They also say "Taiwan Made", not "Made in Taiwan".
Here's a 5 amp Omron solid state relay in the same form factor on Digi-Key.[1] $24.75. Digi-Key doesn't carry Fotek.
Here's a teardown of a counterfeit relay on Instructables.[2] The author had designed these relays into a larger system and was getting warranty returns of the entire product. It has components sized for maybe half the nameplate current rating. There are complaints on forums from people using these for 3D printer hot bed control, brewing control, freezer control, and "grow rooms". They're a popular way to get an Arduino to switch large AC loads. Under higher loads, some units have been observed to melt. Others failed, sometimes into the ON state.
