"Great Remote - and Great Logitech Support"4.5 starson by CorkyMuldoon
Pros: Ergonomic. Motion sensor helps in locating the unit.
Cons: Separate accounts necessary for multiple remotes
Summary: This is the second 550 I've owned. The first one suffered from a backlight that wouldn't go out, severely limiting battery life.
I contacted Logitech technical support and was asked to reflash the unit's firmware and to reprogram to see if would recover. It wouldn't - and I notified Logitech of same. To my (pleasant) surprise, Logitech responded quickly and notified me that a replacement 550 was in the mail to me. On its arrival, I simply had to throw the old one away (no need to RMA). I was also told that the defective 550 would be deactivated and wouldn't be able to receive any updates or changes to configuration.
Logitech has a remarkably large database of devices to program their remotes. They're also learning remotes, making it a snap to add custom functions to buttons that might not be available via download.
This units are highly customizable, making it easy to add specific commands to mute the TV when switching to the HT's AVR, etc. One previous poster said it could take some getting used to, especially if you're not particularly tech savvy, but with a little patience you'll have yours doing everything except tying your shoes for your.
There are three Harmonies in my household (soon to be 4). It would be nice if the desktop software used to program the device would support multiple devices under one account - but that's the only drawback I've found.Updated
I'm on my second Harmony 550. While the first didn't suffer a total failure, it did "misbehave" by keeping its backlight lit. This, of course, would drain battery life quicker than the unit should.
I called Logitech Tech Support via e-mail and soon received instructions on how to effectively "hard boot" and "soft boot" the remote in hopes of resolving this minor issue. Each proved unsuccessful. After letting Logitech know that these approaches didn't work, I received an e-mail indicating that the defective unit had been deactivated and that a new Harmony 550 was being shipped to me!
The unit's only design flaw - as indicated in the CNET review - is the arrangement of the numbers on the number pad. You've got to be careful directly inputting these (and it would probably be helpful if you had tiny fingers). That, howevever, is about it.
I use the 550 in the bedroom, so its motion sensor feature is especially helpful & noteworthy!
