I live in central valley in California and there is always traffic, purchased the HFA more than a year ago before my husband and I were to travel across country for a few months. I wanted to witness what the HFA was about and what I noticed was the effect it had on my husbands ability to concentrate and communicate in a much more relaxed manner seemed no matter what came up it was handled with ease, which brings me to this story in May of 2017 we were traveling the Los Vegas area to visit some National parks when there we were in 5 lanes of traffic and I was explaining to husband gently that he needed to get in the far right lane so as not to miss the turn, he ask me to get in the back of the RV because I was making the tense moment worse so I turned it over to universe, well about five minutes later all HELL broke loose and when we were able stop he explained to me that there was no possible way that he could see how he had avoided a major accident and ended up right where we needed to exit! I am so glad that I purchased the HFA the differences were very noticeable and it will be on board when we travel this year. Thank You Peter
