These guys were great, used the coupon and it worked, $10 smog. My smog check took less than 15 mins and I was out the door once my car's sensors finally started reporting readings.
I had recently disconnected the battery cables and didn't drive the car much before getting it smogged. The mechanic told me to drive it for 50 miles at 55 mph. I had to do a couple 50 mile trips for the sensors to finally report readings. I'd bring my car there for repairs, seem like straight shot guys who didn't try to sell me anything or create problems that aren't there. Will use them again.
