Mine were bought from loca Autobahn who also told me the same line, no issues with them. First unit would randomly go all over the place and scared the shit out of me when it went up to 900° while on the highway. Gauge was swapped out after excuse like above was given. New one worked for a week then fark me, again, rock-show.

After a well place thump (yeah, I smacked it), no issues again till the other day when I washed the car (and under the bonnet), the thermocouple and lead got wet.... Took a solid day to dry out and work again. The SAAS stuff is cheap-n-nasty. The next gauges i use will be likely something like Autometer.
Thanks for the reply Benji.
Since the last posting I've taken the car to an autoelec and had the wiring checked out. He spent nearly an hour on it and said the wiring was all OK and he could find no reason why the gauge shouldn't work. I went back to Autobarn, showed the autoelec's invoice and asked for a whole new everything. Got a third guy this time and he said the same as the previous two guys - no SAAS gauges have come back for warranty yet plenty of Autometer have. Anyway, he replaced it. Got home and carefully fitted it all up and because I didn't trust the thing, I only twitched the wires together. Bloody thing didn't work! Then when I touched the wires to untwist them it suddenly worked (the engine was already hot). So I thought, nothing to lose, I'll crimp everything together. So I did and it worked and it's still working. I don't know if they're crap or not but it's put me off them.
