Nightstalker 170 Spotties

I recently bought a set of Nightstalker 170's partly based on a good review of them in 4WD monthly last year. Their review rated them "best value for money".
What they did not tell me was that they didn't come with a relay, didn't have enough connectors, only had 2 x short thin pieces of wire and had no instructions to wire them up. By the time I bought the extras, I may as well have bought Narvas or Hella.
I rang up the national supplier of Nightstalkers whose name was on the packaging (Hansa Parts in Melbourne ). The guy I spoke to was pretty rude and basically told me I was a moron for not knowing how to wire it up without instructions and should not have expected a relay in the kit as "how would they know what relay I needed."
Supercheap Auto, where I got them from were pretty helpful and got me a copy of instructions from another brand's packaging and checked the other Nightstalkers on the shelf only to find they were all the same.
Anyway, they are fitted now and seEm OK - but beware when you are buying these things as they can cost alot more than the shelf price if they have crappy or incomplete wiring kits.
