Query: Not Very Durable

I've purchased several of the Logitech Harmony remotes in addition to this one. When these things work they are great. But beware that they stop working after 3-4 years. One of them the screen just stopped working, another couldn't be updated through its USB connection and another resulted in the remote just stopping. The last one I purchased is already showing signs of problems after 8 months. The screen will just go blank. When you add up the cost of replacing the remote it isn't worth the convenience that they offer.
