Going through this process has been an eye opener and mistakes were made. Zion at this shop has made it a little more bearable. He’s responsive and more importantly on time with a positive and supportive attitude. I’ve never had issues getting in contact with him at the shop. Install and removal was quick. Aside from the company, he has been great to work with. Of all the horror stories at other shops I’ve read, highly recommend this location if you’ve put yourself in this position.

I’ve been getting my breathalyzer calibrated by Zion for a while now, and I couldn’t be happier with the service. He’s incredibly helpful, knowledgeable, and always makes the whole process quick and easy. Whether it’s answering questions or making sure everything is running smoothly, Zion goes above and beyond and makes an annoying requirement a lot less stressful!

Zion is the only good thing about this company. Great kid, great empathy, he is amazing. The company on the other hand would get a half a star.
