I have a "One" and a 659. My 659 has a rattle; like something is loose inside of it, been that way for 3 or 4 years but worked great up to about 6 months ago, now it seems like it doesn't work so well.
The "One" is really nice. For some reason, it isn't holding a charge anymore. If I leave it off the charger for 24 hours, it is almost completely dead. I hope it's just dirty contacts, as I really like the remote. The layout is 100% better than the 659.
