Used them twice in the last year for smog checks. Very fast and reasonable prices. Friendly and nice to deal with.

  Dropped by with no appointment for a smog check. Was serviced right away. Had to go back since i just changed my car battery. The guys explained everything very clearly. Same good experience when i came back. Very good service. Very friendly people. Will definitely recommend to my friends and clients. Reasonable price!
Thank you!

  Yelp hours said open at 8am. I came at 9:30 last Friday and waited until 10:30 and no one showed. This was the 2nd time too. This is unacceptable. I went over to Fullerton Smog and was seen right away. Passed smog check and was on my way in less than 10 minutes. Never return to stop and smog again.

  Very happy with the service I received here at Fullerton "Stop N Smog". I had no appointment and I was able to get my smog check within minutes. I did not get the employees name, but he was very friendly and professional.

  Really opens at 10(ish), and had me wait an hour just to tell me they couldn't actually do my smog check
