Worst Interlock company. The devices are big and old and they dont work properly. Each week it said I refuse to bow when I didnt. Plus the connections are really looseand interlock. I ended switching to another company

This was the worst experience i have ever had in any type of business. Mike was the absolute worst he was offended and very rude yet since the breathalizer was put in we had been at that location every week. The second that we got it out car worked, we had to go with a new location and it has been a complete different experience.

Good service. fast and easy. still got 11 months to go lol

Take it from someone who is still under contract.... Find another company, I cant possibly imagine any other company worse than alco alert.

Delicious

Theres this one guy that misses everything up that works there he thinks he owns the place and he thinks he could talk to you however the whole he wants I was going there not a new more now Im going to the West Covina location where they are friendly

Had a great experience here! Staff was great and the prices reasonable. Do recommend!

Brian is friendly& took care of buisness.

Went in to get breathalyzer installed and had a great experience with a young man by the named of Michael who did his absolute best to install my device and explain to me step by step how it works, ever since then i have not had a problems with my device. he was very helpful and had a very positive attitude on helping me out . thank you alcoalert montebello .

The office staff is horrible, they treat you like you need them, they walk around with attitude

Gabby is the best. Very professional. Quick and efficient.

Very rude service.they charge for you to breathe in there. The technician who puts on the device feels like he owns the company.

Cool staff. .
