When it works it works great! But it is not reliable 100 percent of the time. When it decides not to work there is nothing you can do to "correct" anything to make it work. You are just out of luck. And forget tryiing to get help from River Past...THEY DO NOT ANSWER ANY COMMUNICATIONS!!!! They have a forum link on their website but it does not work either. I've written them at least 4 times in 4 months BEGGING for their help and they just ignore all communication.
