I had an old 670, screen has died. Thx Logitech, they gave me %50 off, so I bought a Harmony One. Now my battery lasts only two days (well I never made it die, but after one day screen shows halfway point) and the range is horrible. I cannot control some of devices unless I aim at them with laser point accuracy. I did not experience this behavior with the original remotes and I tried 670 (which still works apart from the screen issue), it does not have that issue either.

Do people have same issues, or do I have a lemon and should I get it exchanged? Will 700 be better (as far as range is concerned)

When I moved from 670 to One, when I clicked on Replace Remote, I lost all my custom buttons. Will it be same way if I do a harmony One to Harmony One exchange?

Thx for your help
