I moved to White City, Oregon and work M-F 8-5. I requested a sat appointment and was told that I would need to drive 4 hours up to Woodburn, Oregon to have this. Ridiculous! I cannot be the only person who works Monday thru Friday

RIDICULOUS
I live and work off a very busy three lane road called Commercial Blvd in FL. I drive a manual VW GTI, so I have to steer with my knees while I'm shifting and using the device. Florida already has the worst drivers I have ever seen in my life, and pulling over to breath into the device is more dangerous than steering with my knees! Also, there are way more affordable & state approved interlock device providers than this one..

Best customer service I have ever had 👌👀👀👍
Look gentleman & ladies, it's really truly very simple it's not rocket science. Think of the money this cost on top of the money we spend on bills, family, or its just pocket change to you, either way it's not worth risking your life nor the lives of other plane and simple neither does the money being wasted there's ubers now if your going to waste money and be safe.so with all that being said if your going to drink then don't drive

You can't install on a Prius
I've been looking for a company to install my interlock system for four months now. Finally find you guys in Flagstaff Arizona. The tech said it wasn't going to be a problem. That he had installed on many hybrids. One hour into the installation he said it wasn't compatible. Very frustrating. I can't carry out my responsibility and get my license back due to having a good car.

Horrible experience
After taking over 5 hrs for installation, when I was told max of 2 hrs, the guy working there told me opposite information from the DMV. Training and proper informing is needed. Had me watch the video on how to operate in a very loud, crowded lobby and video gave inaccurate info on how device works.

I WOULD NOT RECOMMEND GUARDIAN TO ANY ONE
I must admit that the customer service representatives are very pleasant before you are an actual customer. I can say that a handful of the representative for example "Melissa Aldas" are very professional. However, once I became an actual customer and I begin to receive the poorest service. The first day of the interlock install, I spoke with a representative by the name of Christina who by the way was very rude. My initial reason for the call was to confirm the pricing for the install. I was quoted $175.00 over the phone and the paper work at the shop showed $200.50. Christina spoke over me the entire time on the call with her, not trying to hear the reason of my call, as a end result I resolved the issue on my own by presenting an email for the install of $175.00. Christina instructed me to pay $200.50, which was incorrect. The $250.50 was for bi-monthly payment if I was to call in by September 2016.
The second time I called, I was transferred to Sarah, who was extremely rude as well. The reason for this call was due to the vehicle failing to start after the install, evening though I passed the test on each attempt. I was trying to explain to Sarah that there seem to be a malfunction between the install, the machine, or the way they install was completed. I expressed to her that the device is not working properly in my vehicle but instead Sarah begin to talk over me stating that there is nothing wrong with her machine because she test them herself before sending them out. The point that Sarah fails to realize it that if she is not personally delivering the machines to the locations herself, then she wouldn't know if something occurred during the time the machine was being delivered. Not at all did Sarah apologize for theinconvenience, try to take ownership of the situation, or even offer to see what she can do to make me a satisfied customer. I asked if I can speak with another individual, Sarah failed to transfer the call, in a laughing manner, stating "I don't see how I'm being unprofessional nor rude." So as an irate customer, I informed her that I would try calling back at another time and disconnected the call.
I then spoke with Christiana again after contacting The Secretary of State for an uninstall of the interlock device who states I owe $150.00 for a early termination. It was not my intentions to terminate the service, but due to the rudeness of the representatives and the failing of the vehicle to start due to the install, I was left with no other chose. No one offered to even replace the device or even try to get me to go elsewhere to have the device installed. The lease the representatives could have done was listen to my problem, apologized for the issues at hand, tried to solve by at least offering to get another device out in the mail or requested to speak with a tech to insure that the wiring was completed correctly. But instead they were rude and over talked me the entire time, after I was a paying customer.
This behavior should not be allowed by any personnel who is representing a company, it is very unethical and very unprofessional.
The interlock install experience extremely awful.

incomplete
I advised the folks at Intoxalock that I was on Social Security disability and there was no mention of indigent status financing help? When I called another company they were right up front with the means to apply for help! They also withheld the total amount to be paid until I started asking more questions. I decided to NOT go with your company because of the incomplete advisement of assistance!
