I have been watching the MLB.TV app on my Amazon Fire tv 4K stick but it was very grainy. So much so that I couldn’t make out names players faces or enjoy watching the games. The buffering was horrible and the lag was awful. So I used the Google machine to find out if there was an Ethernet option and lo and behold there was. After I purchased this item I didn’t think it was a bad price, I also had to buy a new Ethernet cable but all in I’m about less than $30 which is fine because not only does my MLB app come in crystal clear but all my other apps have zero lag. Win win for me. I highly recom
Edit Update 20211118:Could be 5stars but reduced back to 4 as the latest interface has some major issues.So the issues with the Ethernet Adapter were fixed about 6 months ago, as the 2nd Gen Firestick had worked well with the Ethernet Adapter since then. However, there are occasional glitches, so I ran tests and keep a background internet speed app running at all times. It appears some Apps just have their own issues and the device itself is working well with the Firestick in the most distant bedroom. So this would raise the device itself to Five stars.However, the 2021 November Firestick inte
I found the device easy to connect and use. It gives me piece of mind to know I’m connect directly to the router for the best possible connection. I do t really notice any visible improvement in quality or speed though.

This adapter works perfectly and is extremely easy to install.

I have 100mb internet service and a centrally located wifi unit in my home that for years has easily supported roughly 10 active devices at any given time. That may sound like a lot, but you take a couple smart phones, a couple laptops, smart thermostats, a couple Echo devices, and throw in a few s
I am hoping to shed some light here on this product without getting into much technical mumbo jumbo (and there is a lot of mumbo jumbo). Do your homework on the mumbo jumbo technical things I am about to explain & it will explain in detail reasons for my test results. There are a million articles on the net explaining bandwidth, latency, speeds, wifi vs. ethernet and so on. Way too much to explain in this review.Ok, first of all the product is very easy to use. It's a no brainer (plug & play). I have two older amazon Fireboxes with ethernet port built in (remember this it's important). I purch
