Fire TV Stick 4K streaming device with Alexa Voice Remote

When service for my older Roku ended a couple months ago, I had no idea which way to go with a new streaming device. I went into my typical research mode and was still undecided, but a couple perks suddenly made it easy to choose the 4K Firestick. As a Prime member, I love the convenient integration of all the subscription premium channels that Amazon offers, as well as being able to choose the standalone apps that were on Roku. Even though I don't yet (or may never) have a 4K TV because no one is currently broadcasting in 4K so why bother, it seemed a no-brainer to get the most updated version and streaming quality of picture afforded by the 4K stick, so the choice was easy and I've not regretted it. However, the stick comes with VERY MINIMAL INSTALLATION INSTRUCTIONS. I'm one of those users who likes to familiarize myself thoroughly with a device and its capabilities before installation, and the 3 steps in the enclosed installation manual left me more than puzzled about customizing the settings. So, I did what I encourage all of you to do -- call $K tech support and have them walk you through ALL THE STEPS. You'll be glad you did. Some things (that I didn't want) were turned on as defaults on the stick, and frankly, it wasn't clear what certain settings even meant or what would be optimal for me. Even going through the entire setup process onscreen doesn't explain many of the choices that can be tweaked. For instance: 1) The remote comes preset to turn on your TV and the Firestick app automatically. I didn't want that. I turn on the TV separately from wanting to stream, and also use my sound bar for all my fine-tuned sound and volume preferences. In fact, I prefer using all my individual remotes. In particular, my TV settings for sound and my sound bar would have been in conflict with the 4K remote default setting, and caused so many more ridiculous steps to turn the TV on or off, the app on or off, or make any volume choices. If you don't mind this default feature then there's nothing to change, but it wouldn't bothered me right out of the gate. 2) I only bought one Firestick because my other TV has built-in apps that are still being maintained by the manufacturer. However, they're two different manufacturers. You cannot use the Firestick interchangeably between different brands (say a Sony and a Samsung) without going through setup each time you switch because setup requires brand selection and only holds one in memory at a time. Plugging the stick into a different maker requires setup EACH TIME you switch from one TV to another, which would be a nuisance. There's a workaround that I learned only from the tech support guy who guided me through setup. During setup, I selected a TV brand that is neither of my two TVs. Therefore, I can easily switch the stick from TV to TV without setting it up each time. No matter how many TVs you have, the trick is to choose a brand that is none of your TVs. Works like a charm, but if I hadn't done setup with tech help, I would never have known that I could switch the stick between TVs and would have just left it on one TV. 3) Some reviewers complain about buffering issues and dropped signal only happening with the stick, and not other devices in their homes. Well, once in awhile I've had a dropped signal, but it comes right back and I've never had buffering issues. Maybe less than 1/2% of the time has this happened, so not a problem, and once the signal is restored it never drops again during the duration of current use. 4) The streaming and picture are spectacular. 5) I waited to get this stick until Google and Amazon ironed out their differences at the end of 2019 so that the YouTube TV app (the best streaming app out there) is now downloadable on the stick. There's a reason for these issues that the tech explained to me: 4K takes ALOT OF INTERNET. It doesn't matter if you have 200 Mb speed, you may encounter buffering and dropped signal frequently, depending on how many other devices in use at the time. Ironically enough, I have a ridiculously slow internet speed that I've never upgraded because I have absolutely no problem running TVs, laptop, tablets, phone, streaming all at the same time here in LA. But, the key here is how much internet you're using at the same time when using 4K ANYTHING, not your speed. I think many of these critical reviewers have 4K TV, plus the stick, plus run alot of stuff at the same time because they have max speed, but they can actually have problems for using too much internet at once, while I have no problems. So bear that mind. I'll admit I haven't yet used the stick's Alexa feature yet because it doesn't matter to me for watching TV, and I have my Echo Dot anyway for other things. I love this 4K stick over any other device, am so glad I went through a formal installation process because (AGAIN) I tweaked even more settings than mentioned here during the process that I wouldn't have known to do or not, plus I have no issues with buffering and dropped signal that affect my use of the device. I intend to buy another stick soon, so I don't have to switch back and forth between TVs if I want, rather than use my pre-installed individual apps. It's so convenient to go in and out of NetFlix, Prime, premium movie channels, Vudu on the stick rather the individual apps, but I have the option of doing it either way..
