My worry, having been stung by fakes in the past (Shimano / KMC chains, Shimano cleats) is that these aren't original. And they tend to break quite easily.
Same here bought lots of Shimano chains from An online auction site starting with an E and all worn out surprising quick even started to check chains before i would clean then to save time cleaning a worn part.
Problem with using copy chains (only my view) is when they wear they also wear your cassette?
My solution is just to look online for a chain on sale online find best price then after checking
Halfords sell the same, go to halfords and buy 5 or ten of them (funds permitting), my issues with chains solved.
Forgot to add Halfords do a price match.
