I've had the spatha for almost 2 years now and today it overheated, causing burnt smell all over the house. I went to walk the dog after I open my pc for a couple of minutes, I left the spatha on its dock switch turned off so that its fully charged when I return, to my surprise when I got back, I smelled a burning plastic and electronics inside the house, I thought that it was coming from outside. When I returned to my desk I noticed that the spatha is deformed and when I touched it, it felt really hot. I saw something melting inside it and dropping slowly. I immediately brought it outside the house as it's almost burning.
Reading so many issues with this mouse makes me wonder what actions does ASUS do about it? It almost causes fire and I think I would not buy another one like it. I'm attaching the photos I've took awhile ago. To those who have this mouse be careful when using the wireless feature. And always check the battery. As it might be the culprit on my Spatha.
