Harmony 890 remote

I have used this remote for 2 months now and it get more frustrating every day. when it works, it works well and controls everything like it advertises. There is definately a reason they put the "remote assistant" in this because you need it continously as the remote malfunctions and/or looses touch with whether the devices are on or off. the worst part, however, is when the remote just locks up for no apparant reason and the only way to get it going again is to remove the battery and reinstall it. Ergonamically, most of the buttons are too small if you have medium to large hands and you either hit 2 at a time or the wrong one.
