This placed changed names I think. I showed up and no one was there. Waited a couple minutes in an empty waiting room that smelled like mj. Then left. I also called while I was in there to see if I was in the right spot and no one answered. Kinda got scared lol. Then left. Found another spot to get my smog. Oh well I guess. read more

Fast, friendly, and efficient. I could not ask or expect better or faster service at a low price that included the certification. In calling around I found that some companies had an additional fee for the smog certification. When I arrived I spoke with Mario. He was extremely cordial and professional. He advised me as to how long the testing would take and delivered on time. I do not hesitate in recommending Pro Stop for your smog check needs. read more

See all

I come here and come from Rialto, they won my trust a couple years ago. I trust them with the smog and are quick, concise, and fast according to how things must get done. I appreciate you guys. read more

I WISH I could give them 5 stars, I really do. BUT I walked straight into a hot box. (For those out of the loop, marijuana). Both gentlemen that helped me were high as hell. I don't judge, you do you, but maybe not in a place of business. Especially, when I have to go continue my day. That being said, I was in and out in under 20min. Cost me $40 with the coupon, but I won't be back. You have free time to do whatever you want, but leave it outside of a place of business. read more

Gr great service, friendly people, knowledgeable, cost-effective, and you don't pay if you don't pass.

Great fast and efficient work done here. If you need smog done definitely stop by. Highly recommend

Kevin was helpful and is honest about his work. They run a shop where the waiting room is well air conditioned which is nice especially on a day like when I went and was very hot outside. They have drinks and snacks for guests while they wait. They acted professionally and explained many things to me about the process. If you need smog check, check these guys out, you can't go wrong. Thanks Kevin. read more

What can you really say about a smog shop? I went there, waited 20 minutes, failed my test because of a defective gasoline cap. Came back the next day and passed the test. They charged me $60. End of story. read more

Great customer service and fast. They were also friendly and very helpful, this business is highly recommended.

June 26th, 2021, took my 2002 Nissan Altima to get the required SMOG Certificate taken care of by PRO STOP Test Only. The business opens at 9:00am and I arrived a couple of minutes prior to be assured that I would not get caught waiting. I was promised that my car would be ready in 15 Minutes. Those two guys worked their magic, and I was out within 15 Minutes as promised! The office was clean and presentable with a nice sized TV hooked up with an Amazon Fire Stick, with a coffee maker and small refrigerator with beverages for their customers. Completely A+, top-notched service all-around. Will be returning for my next smog and would recommend to all friends, neighbors, and strangers in need of an establishment as theirs. Thanks Again! read more

Fast and efficient. Friendly staff. I will definitely come back in future and would recommend to other to go to this place.

Visited these guys a few months ago and had a perfect experience. I called to ask if they had any availability for a smog test that week and they said I was able to come in whenever suited me that day. The place is very small and was manned by two young guys who were both friendly, polite and genuine. As a woman I felt relaxed there (always like to point that out to other women!) They offer snacks/water. They saw to my car straight away and completed the test extremely quickly. Overall I'm very pleased with the service and would definitely visit again. read more

Super fast and easy! I came in as a walk in, and was finished in about 10 minutes. I wasn't able to print the $40 coupon because I don't have a printer, but they honored it anyway. Staff was polite and professional. I definitely recommend it. It's also comforting to know, if you don't pass,you don't pay. read more
