If I could give it zero stars I would. Worked fine for the first couple days I had it, and when I went to try it for the first time it suddenly didn't want to work. All that comes up is a blank screen as soon as I start the Dasher app. I thought it was a connection problem at first so I wasted 30 minutes of my life and wasted gas trying to get it to work. Then I figured out it was the app itself and how lazy the dasher support group is. Turns out I'm not the only one having this problem either.
