I've had the Harmony 880 for two years and when it works it's great. The rest of the time it's an expensive doorstop. The main problems are battery recharging and upgrades.The battery charging cradle is very persnickety, so it's possible to place the remote in the cradle and miss the charging spots. The result is a dead battery instead of a fully charged one.The other problem is the difficulty in upgrading the remote. The Logitech Remote software hangs at 3% and never upgrades the unit. No firmware upgrades, no updates to equipment. If you don't get the programming right on the first try, forget it.
