First, the users manual is not good. However, customer support makes up for it. I emailed them a question on a Friday evening and they contacted me very quickly. We discussed the problem and I went to bed. The next morning, Saturday, I found they had answered my question and solved the problem. I responded and they emailed me back, on a Saturday, to ensure that the problem was fixed. Who does customer service on weekends? Apparently, Family1st, that's who.
