The main downside is that finding documentation on how to use it requires you to be a google wizard. However, I found what I needed to know and was very pleasantly surprised at how well it works and how well thought out its features are. A simple example: if you turn the volume to maximum, a small tone will be inserted to let you know that you are at maximum. Nice touch, they didn't have to do that, lots of examples like this. I was wondering how well it would work without a display, but it uses voice mode for communication mode, bluetooth pairing status, etc. and does a very good job. I use it to turn antiques into interesting streaming columns.
