Switched from a Spectrum DX3R to a DX5R a year ago and no issues and no problems. Wish I would of switched sooner.
The new DX5 Pro is a step up from the 5R as Spectrum listened to the users and made some nice improvements.
And no problems with making adjustments... like any radio you have to learn how to navigate the screens and understand what each option does...
DX5 Pro on my Christmas list....
