Bests & Worsts Reviews from Amazon

My Order was placed August 1, I received the Chromecast on September 10th. It was back-ordered so that's understandable. However, the unit I have never worked right. Streaming for my pc, my iphone, my ipad, my sons laptop - works for a short time, then the Chromecaster reboots/resets itself. It could be iTunes, YouTube or anything cast from Chrome itself using the tab-cast method. Same results regardless. Works for a bit (5 or 10 minutes) - then boom - reboot. And once the reboots happen, it seems to shorten the time until hit happens again. I called customer service and at first they were very helpful. Trying any number of things, resets, moving it to a different hdmi port on the tv, moving it to another tv. But none of this helps. It still happens. And the customer server has gotten worse and worse. At first they stayed on the line and waited for the result - then they moved it to emails, where I had to wait days if not longer in between replies and those replies were useless, suggesting things that had already been tried or demanding things like proof of purchase and then not replying for a week after it's provided. I would have sent it back and gotten a replacement but they were still back ordered in September and I figured Google would actually take care of their customer. I guess that was my mistake. Here I am, a month later and no resolution. No response from customer service and no working chromecast.
