Pros: Easy to program, software works well. Database for the remotes is enormous. This remote has plenty of buttons without being overkill.

Cons: Build quality is inferior to my Harmony 550 purchased several years ago. The 550 feels sturdy, the 520 feels cheaper and tends to make creaking sounds when pushing some buttons.

Overall Review: Overall happy - this was bought for the bedroom TV and DVD player, it does this role well. Worth it over cheaper generic universal remotes.

Pros: -excellent value for money -controls my entire home theater setup -wife/in-laws approve, they no longer have to use 5 remotes to try watch a movie at our house... LOL

Cons: eats batteries; sometimes misses shutdown of certain items (i.e. TV), but is easily resolved by controlling device and turning off

Overall Review: Windows 7 support for certain pieces of the software do not work.

Pros: NONE yet If they allowed a zero I would give it that.

Cons: Unit was DOA. It was shipped with batteries to install BUT the unit already had batteries in it and the batteries in the unit had leaked. The unit clearly appears to be a used unit that has been sold as new by harmony. I am in process of returning for a new unit it will be interesting to see what I get.

Overall Review: This is the first product I have purchased from logitech/Harmony. This is not a good start. I am not pleased with recieving a runined unit that was used. Packaging was factory plastic formed without any evidence of being opened. So the conslusion would be that harmony supplied it to newegg as I recieved it.

Pros: All configurations went through beautifully, set this up for a client. Take it out of the package, install the software, plug it into the computer and walk through the steps. Everything from the simplest to the most complex button routing available.

Cons: None that I can think of.

Pros: Runs all my devices. Sony A/V receiver, JVC DVD, Samung LCD TV & VCR, Amino cable box. I've replaced 3 remotes with 1. Fewer buttons (on this remote vs. other universal remotes) is a plus, not a minus.

Cons: The setup software is clunky. It 'downloaded updates' and then quit & restarted itself 3 times in a row when I first installed it. I guess it downloaded new updates every time, but all the restarts made it seem broken. Now that it's installed, I've found it pretty functional, though it's ugly and seems slapped together. The LCD screen is small and a little hard to read sometimes. Backlight is good, though. No indicator for how much charge remains in the batteries, or any estimate of how long until they'll need replacement.

Overall Review: Waiting to see how this thing is for battery life.

Pros: Remote works with my LG LCD TV, Motorola Set-top box, Onkyo HT-S5200

Cons: No software support for Linux

Overall Review: Now I just need to find an IR receiver for my computer

Pros: This remote replaced another Logitech (676). Did not have to re-program, select replace option and you're done. Hope this last longer than my 676.

Cons: None

Pros: Easy, comprehensive, good-looking

Cons: Feels like a cheap piece of plastic

Overall Review: This remote works great, is fairly easy to set up, and does absolutely anything you need it to. The one complaint I have is that it feels like it is terribly made. Whenever you press a button, it feels like the remote is going to fall apart. The plastic is just flimsy
