I use SOBERLINK for convenience. I have an intense business that I run and operate. I also work many hours and I have many client meetings. I have to travel a lot. It much easier for me to do this multiple times a day then to go to a lab. It is a little on the costly side, however, if I was to be pulled away from an important meeting and schedule a lab test, it would hinder my business. It’s not on the cheap side, but for me it’s worth it.What are the pros and cons on using Soberlink(which is not a requirement on letter from FAA) in addition to the required 14 urine ETG and 10 drug panel in 12 month period?
