I just loved the glow pattern on the 880 so much, I had to take a picture of it in action.
Illuminating Blue Backlight
Don't you just love this glow? It's actually better than the other Harmony remotes. The only way I can describe it, is that it doesn't have an "All over the place" glow, but has more of a specific glow for each button.
Background Images
And yet another exciting feature of the 880. You can upload an image (160KB maximum) and have it displayed on your remote's background. In case you haven't noticed, the background image you see to your left is of my cat. Logitech only permits images of cats to be uploaded. Dog images are not allowed.
I'm kidding.
Slide Show
When your remote is on it's recharging base, the Slide Show option allows up to 8 images to be sequenced in time intervals of your choosing (1-10 seconds). This is a way to show off your photography, without even mentioning it. While sitting on your table top or anywhere that might catch a curious eye, the Slide Show is one of the Logitech features which makes owning a remote enjoyable. Logitech says the images uploaded should be 128 (W) x 160 (H) pixels, and 24-bit color depth at most. If the images are smaller, just like the background image, your image will be re-sized to fit this proportion.
A helpful tip if you don't want a slide show to appear at all. Create a black image (128 x 160), and then upload it into the first two spaces. Then, when your remote is charging, you will see nothing but a black screen. In some cases this might be necessary because the remote puts out a rather bright display. It will certainly illuminate any place you put it.
I've gone ahead and created a black image for you, just to make it more convenient when you purchase the 880. It's also a thank-you for reading this review. It is the size recommended by Logitech, so all you have to do is download it and upload to your own Logitech member website:
