No experience wth the hearing aids as I have Phonak Naida UP.
But with the remote control, I have the My Pilot and I love it.
When I change programs on my aids I have to cycling through my 5 programs to get to the end (mute) but with the My Pilot I can go from 1 to 5 or 5 to 1 (5 because I have 5 programs, it could be more or less), so it is a lot easier to say to do number 5 the mute program.
With the Pilot One, you can only change the volume on both aids at once, with the My Pilot, you can change each ear on their own or together which I find helps.
I also find I get confused with what I am on when I change them on my aids, with the display on the My Pilot, I know exactly what I am on.
I find with the My Pilot, my battery will last 3 weeks before I have to charge it so I dont find it does not last as long because of the rechargeable battery.
The ComPilot could be a good thing as it is a remote and other things as well, but from what I see of it, it does not look like it would do as much as the My Pilot, looks like it would do the same as the Pilot One.
