Taking the 880 out of its packaging, I could immediately see improvements. I am excited to say, no more battery worries and running out of batteries is a nightmare of the past. The Harmony 880 now has its own rechargeable Li-Ion battery and charging station. The buttons have been rearranged, simplifying the remote process even more. The buttons themselves have been redesigned to "integrate" into the shell of the remote. The overall size and shape of the Harmony 880 has remained the same as previous models. Sometimes you just can't change a proven successful style.
