These seem much better than the $2-3 ones you can get. They come on with a reassuring click and seem very well made. They have a resistor wired in parallel with the coils to prevent internal arcing so that ensures a longer life. I got 6 of them at the moment and will buy these again in a heartbeat if one fails (which I doubt).

Reliable and functional, these relays work fine and haven't had any problems since I installed them in my Jeep

Bought 8 of these to fit in Hella 4 way relay block. I love these, well made, feels solid, no annoying click with on and off. Overall a good product.

Did not use it because relay box kit was larger than I thought and would not fit intended application.

Exact factory replacement, quick snap in installation, prompt delivery. $10 fix for a mower that was blowing 30 amp fuses on the starter circuit. A cheap fix by "fixing by substitution". Had no idea what it was, but was at a dead end, and gave this inexpensive unknown part a shot. Fixed !

Garbage! These look nice, feel nice, and are made of good materials. I bought 5 but not one of them worked correctly. It seems that they are not built correctly as the circuits inside the relays arent properly wired / connected and they function improperly. Some left the circuit open, others only had one circuit working. At first i thought my woring was bad, but i used a generic relay in place of these HELLA relays and everything worked fine. Switched it back and these again dodnt work. If these worked properly theyd be a very nice unit because the build quality is nice...overall though as is im very dissapointed and theyre going straight into the trash since they're useless. I like HELLA products but I'd stay away from these relays! .

Not the type of relay I needed. This switches between 87a and 87b. I am not smart enough to know what you'd need that for; maybe turn signals or something? I just want two 87a terminals to run my off road lights directly off the battery. This has taught me the difference.
