Excellent TrustScore Rating

January 14, 2026

"Honestly I was bitter at first. But that was because of my own issues with it being mandatory. Other than watching the price rise dramatically, I think smart start is a thorough company that truly separates drinking from driving.I think every car on the road should have one. I recently had one reinstalled into my new truck to do the final 4 months. Shauna was excellent. I was able to get it installed the same day. She was intelligent and professional and went the extra mile to make sure I was content and even gave me a break on something that im sure she didn't have to. Once I settled in and grew up, the company grew on me and I was able to see it for more than the nuisance it had began with."
