Works well and programming was easy as it just took my settings from my old Harmony One. Buttons are not as intuitive as on the older ‘One’ and you have to watch out not to brush up against the touch screen. Does seem to work faster than the ‘One’ and it is not as picky wanting you to point it directly at your devices. If it loses it’s charge, it seems to get a quicker boost from a shorter time when you put it back in the charger. The battery is not replaceable like the ‘One’. Overall, a capable device; however, not the upgrade I was truly hoping for.
