Identical in purpose to the other remotes in the Harmony Line, the Logitech Harmony 880 offers an excellent balance of features which places it squarely in the upper middle of the Harmony line. It allows you to control more devices than the 6xx and 5xx models but is strictly IR and therefore line of sight as opposed to the RF capabilities of the Harmony 890 and Harmony 1000. In terms of ease of use, the 880 (as well as the rest of the Harmony line) surpasses virtually every other brand of remote available. Presently, only Universal Remote Control Inc offers an equivalent level of ease of system control, however; the brands differ significantly in the features they offer. URC remotes typically allow you to control more devices (up to 255, vs. up to 15 for Harmony) but, they are also generally programmable only by the dealer.
