The relay itself is a standard SPST 40amp JD1912 relay that can be found anywhere. They’re sealed and come with a removable stamped steel mounting tab.
The harness is super light and only suitable for light loads. The contact leads are marked 1.5mm2 which equates to 16 AWG wire not the 12 AWG in the description. This wire is maybe good for 15 amps not the 40 that the relay can handle. The coil leads are marked 0.75mm2 which is about a 19 ga wire, fine for this application. All non-tinned copper stranded leads
Also the description refers to a fuse on the inputs, this is also not the case. No fuses anywhere on this assembly.
Its a decent price is you plan on just using the relays, the socket and harness is not very good

I used the “JUZITAO 8 Pack JD1912 Car Relay Harness Set 12V 40A” to set up lights on a go cart and a couple Chinese ATVs. I first tested with a 12v power supply and all 8 clicked over as expected. This set of 8 is about the same cost as one relay with socket at an auto parts store. Wiring diagram on relays is accurate. Overall, this is a great deal and I highly recommend for wiring vehicle lights.
