This is what I compare the other digital keychain to (Digital Photo Frame 1.5" LCD Picture Album Keychain - Black). This one is well worth the money. It has great quality pictures, software that you use with the device. It was a little tricky getting usedto the software at first, but pretty easy now. You have to have the device plugged in and then start the software after clicking on photo update on the device. Then you may add and edit your photos as needed. You charge this up by plugging it into your computer by USB. I found that certain types of cell phone chargers work with this. My moterola trackphone charger works with it.
