WiFi Range Incredible! MUCH faster app load times

I got the new Streaming Stick 4K+ as a gift! I had the older models of the streaming sticks. I can, without question, tell you these newer models are MUCH faster and the WIFI ranges are SO much better!

Why are the Roku sticks such crap? I've had Roku since they came out -both boxes and TVs. I've never had a bit of trouble with any of them. But this is the second Roku stick that has been just plain awful. The first one I bought a few years ago thinking it would be easy- no wires etc., but it just got to the point where I don't want to work at all. I called and they gave me a replacement. It works fine. But we have to take the batteries out of the remote after every use. Otherwise it just drains the battery's dead. That one got moved to the guest room. I thought a few years later and technology would've improved. But apparently not. This new one does not stay connected. Every time I turn it on I have to watch it go through the "reboot dance"- every time. Then I have to reconnect to the Internet - every time. Then I can go to the homepage and select the app I want. Also I find the remote the to be sluggish and Unresponsive.The other Rokus in the house and camp work fine- even the really old ones. I should've known better than to buy another Roku.

Bottom Line No, I would not recommend to a friend

Fragile and Proprietary WiFi Dongle

I bought two of these sticks and will never get another Roku with a WiFi dongle due to problems I've had. The first stick's dongle got snagged on something and after that the Roku would power on, but not connect detect the wifi adapter. Ok, probably my fault so I got another one. This worked and after a while I decided to get a replacement wifi dongle for the one that broke. I'm not sure which one it was, but later I began to have the same issue with the wifi adapter not being found by the Roku stick. To my knowledge, the second one to fail was not pulled, yanked, etc. The one working wifi dongle has been working for a few years now. I would purchase other Roku streaming devices in the future, but only they do bot have a proprietary wifi dongle.

Well. This is just muy opinion. I bought this 4k stick a month ago, it doesn't really work for live Spanish Channels un less you are paying for a TV plan with you cable provider, it does work for other apps but specifically doesn't work with Spanish TV channels, I don't really see the point to have Roku stick if you have cable plan,. As soon as I canceled my TV plan my Roku live app stopped working, I called support and they told me with out the plan roku won't work for live TV, .

I've never had trouble with my old Roku, but this one (which was a gift), the 3821x, won't work on my newer TV (it seems to work fine on an old one I no longer use). It keeps "flashing" on the Home screen. It's on, it flashes off, then it's on again. I can't seem to find a fix online.

Not even 1 year old and the battery will not charge. After spending 30 min with the customer chat line it dropped out! If you look on the customer support page you will see I am not the only one with this problem. Not happy with is one. Get the old style.

Why not just power these through the tvs powered USB inputs .. its not cord cutting if you have to run extra wires.

Official Response by Roku - BV

Hi Nick, thanks for your feedback! Please know that you are certainly able to use the TVs USB ports to power your Streaming Stick, rather than plugging it into a wall power source. We include the wall adapter plug for those whose TVs may not have an USB port, or those whose TVs may not produce enough power for the Streaming Stick. Try and out and let us know how it goes.

Although it's great as a remote and streaming as advertised, this new version will not connect with your phone's app to use as an additional remote.

Official Response by Roku - BV

Hi Chief, thanks for the review. It sounds like you're having some trouble getting connected to the Roku Mobile App and we're here to help! First, your Roku device and mobile device must connected to the same network to communicate successfully. Sometimes, a user's mobile device is connected to the home's 2.4 GHz network and the Roku is connected to the 5GHz network. To confirm the network on your player, go to your home screen followed by Settings > Network > About. If you've confirmed that they are both on the same WiFi connection, be sure that your Roku player and mobile device are both on the latest software update. Once complete, be sure to restart each device. Finally, please ensure your Roku device and mobile device are not using the same IP address, using a public IP address, or using a VPN on your mobile device. We offer more in-depth troubleshooting details on our support website: https://support.roku.com/article/115001480188. Happy Streaming! Roku Customer Advocate

Official Response by Roku - BV

Hi Adrian, help has arrived! You'll want to be sure to use the charging cable that came with your new Voice Remote Pro. Not all cables are created equally and we've noticed that customers who use alternative cables may not have the best experiences. Additionally, please try to press and hold the pairing button on your remote for 15 seconds to see if the remote charges. If this still does not work as expected, you might request an exchange from the retailer that you purchased from. We hope this helps! Roku Customer Advocate
