Pros * Software relatively easy to use and found all my devices
* Can even program my ceiling fan controls!
* Comfortable in your hand
* Button layout is thoughtful
* Can customize almost every button
* LED screen is flexible
* Eliminates remotes!
Cons * Activity presets have some baked in settings you can't customize
* No out of the box PS3 support (although I blame Sony, not Logitech)
* No RF support
* Only supports 6 devices
* No charging station (just USB to wall cable)
Summary My first foray into specialized customizable remotes. I am real happy as this things does what it is supposed to do. RF would have been nice, but it isn't a deal breaker. The feel in your hand is nice and it comes with 2 rechargeable batteries. Responsiveness is nice and sometimes even feel better then the original remote.
Preset "Activities" are a mixed blessing that do basically what they are supposed to do and allow you to mix controls on your remote (like having the volume buttons operate your receiver while the channel buttons operate the cable box). Although, the "Watch Movie" preset activity forces my Xbox 360 to be my DVD player by default and the software won't allow you to remove or change it. I have also found the software to be to inclined to make you want to change your TV inputs when you change an Activity, even though all my inputs change at my receiver. An option that states "input change unnecessary" would have been nice. Some of these things can be done via a workaround, but it would have been nice if they were easier to find in the main Activity menus during setup.
The only device this didn't cover was my PlayStation 3 (which I use for a Blu Ray player). The reason is Sony stupidly chose to use Bluetooth for the PS3 remote interface and this Logitech remote does not do Bluetooth. You will need to buy an extra device to allow for PS3 control. The software will map PS3 buttons, though.
Only major negatives I can find were some of the baked in Activities features and non intuitive setup options as well as the non support for PS3 Bluetooth control.
Pros consolidate all remotes
Cons I find myself needing to hit the help button constantly. the activity setups are not accurate.
Pros None - won't set up.
Cons Can't set up. Can't get it to work and no help readily available.
Summary Logitech needs soem serious upgrading of their customer service.
Pros None - this remote delivers on none of it's promises.
Cons Poor battery life, even with new rechargeable set-up; Doesn't remember key commands; constantly tries to correct non-existent issues when it's working properly; says there is a problem with components when there are none; sets inputs to incorrect settings
Summary Worst than my previous Harmony; two-for-two: they were both worse than just programming a Comcast remote and dealing with less functionality.
Pros Windows and Mac OS support, plus Firefox support.
Logitech Harmony Remote 7.7.0 software has significantly more function and flexibility than the default online setup. Good enough for my modest needs.
Cons Documentation didn't indicate that Harmony Remote Software 7.7.0 was a downloadable alternative to the default "simple" online configurator. Backlight and a charging dock would be nice, but not essential for me.
Summary I tried the more "advanced" Acoustic Research XSight Touch AARX18G for an hour or two and gave up because the software would not work. I know the Harmony doesn't have a touch screen or backlight, but what good are these features if you can't even set up the Xsight. I exchanged the devices at the retailer and the Harmony worked correctly the first time. I did switch to the more feature-rich downloadable Remote Software 7.7.0 after first trying the default simple setup, because I wanted to rename the Activities (Logitech could improve their documentation included in the box so buyers could make a choice up front). Logitech's huge online database of devices included all four of my home theatre units (Z550 amp, Pioneer Elite BD DVD, Octava 4X1 HDMI switch, Epson 8350 projector), so I didn't need to do any IR "learning" from my old remotes. I only had to manually add one IR step to each of my Activities to turn off the LED on my Octava 4x1 HDMI switch. I may try to work with my Logitech Z5500 audio amp settings to see if there is a discrete "power on" and "power off" instead of an on/off toggle, because sometimes it gets out of step, especially if you are making configuration changes and forget to do an "all off" before updating the remote on the PC.
