Not really as their is not much visible ware. What is happening is that the power connector is getting a little harder to insert. It feels like it catches and then with a little extra force slides on OK. I have only started to notice this in the last couple weeks (had my empeg since September I think). My assumption is that I am wearing down the polished metal in the connector somewhere, but I don't really know if it is on the male or female end of the connector. This may never be a problem, but it is what started me thinking setting up some sort of sled for home. -Mike
