It is very easy to set up, install and use in our vehicle, I like that it does not require any extra hardware or software to be installed.
The only thing I do not really like about this system is sometimes when you are driving with other people who have their own phone I cannot hear what they say unless we both speak at the same time - but once I am able to listen again everything works fine! Great product for hearing impaired drivers. We no longer need to ask others if there's something going on because it will notify us if someone calls out to us from behind so you don't miss anything.
