I have been through several Harmony 650 remotes because the buttons would wear out with use over time. I was hoping the Ultimate One might be more robust given that it's over twice the price and this may yet prove to be the case. However the Ultimate One disappoints on a few fronts. The buttons are smaller and more difficult to use. The button layout is not as intuitive being a big departure from the layouts of the 525 and 650 models that we used in years past. Also, trying to use the ‘gestures screen’ for things like volume control results in wild swings of sound levels as a small gesture would result in a large change in level.
