Bests & Worsts Reviews from Amazon

I have owned Fire TVs since the 1st generation box (2x 1st gen, 2x Sticks, 2x Pendants), and I have never had a problem with the hardware or streaming performance. These 4k Fire TV Sticks have put an end to that good luck. The main problem is an audio issue that causes the sound to cut out every 5 minutes or so of streaming video. It will stay cut out for several seconds, then come back with a very noticeable delay (500ms or so) which makes Netflix or streaming TV unwatchable. I have also seen strange picture glitches when streaming 4k HDR content. Other issues: - the device becoming unresponsive and needing a hard power cycle to come back on - remote not waking it up from sleep I own two of these, and both show the issues. One is connected to a 2017 LG B7 OLED, and the other to a brand new Vizio P65-F1. The issues exist if using the TV's speakers or the optical-connected soundbar and HDMI ARC connected receiver used with the TVs respectively. Look at the one star reviews before purchasing. This is not an isolated issue, and it needs to be fixed before purchasing. I will submit a return on mine and update the review if the new ones do not have the problem.
