I have the 720 and have been using it for 2 years and like it very much. The new update that just came out even makes it a better choice. All screens flow better from one to another and the selection buttons now are better identified and a bit larger. Although I have the 720 and it is okay in direct sunlight I still find it hard to see. If they had the same resolution as Dynon or Garmin the Ifly would be hard to beat for price and features.
Just my .02
