s of more apps in many different categories.Here are some points to consider when deciding on which model of Roku to buy:

1)If you need to connect by WiFi in a room far away from your WiFi router,I would recommend the Roku Streaming Stick PLUS or Roku Ultra.

2)If you have a 4K TV,I would recommend the Roku Ultra or Roku Streaming Stick PLUS.

3)To search for content using your voice,go with either the Streaming Stick,Streaming Stick PLUS or Ultra.All 3 of these models also have a remote that can control the power and volume on a TV.
There is also a Roku app for Android & iPhone/iPad that lets you use your smartphone/tablet to control any Roku device and use your phone/tablet on-screen keyboard or voice for searches.

4)If you want a wired ethernet connection,go with the Roku Ultra.

5)If you want to connect to an old TV with RCA/Composite audio/video jacks,you will need the Express PLUS

6)The Express models have a remote where it has to be pointed at the device,unlike the other Roku models.

7)If you are only going to buy one Roku device,I would recommend the Roku Ultra.The Ultra has many unique features that the other Roku models don't such as:
-Gaming buttons to play video games
-Remote finder to find a lost remote control
-Ethernet port for a wired connection
-Micro SD card slot
-USB Port
-Night listening mode (this lowers the volume of loud,explosive sounds and raises the volume of soft sounds like whispers.Very useful!)
-Headphone jack on the remote for listening without disturbing others

For those who have not used a Roku before,here are some tips that might be helpful:

1)There is no monthly fee to use a Roku.There are many free channels/apps with free movies,music and TV programs and some people use Roku only for the free channels and do not pay any fees.

You do NOT have to enter credit card info if you only wish to view free content and you can always add credit card info to your account later for paid channels/apps.If you plan on viewing free content only,I suggest setting up a Roku account before you activate the device.When you reach the page to enter credit card info,some browsers will show a "Skip,I'll add later" option at the bottom.If you do not see this option,simply log out of your account,then log back in.You may have to then enter a different activation code for your device if you skip entering credit card info during device set up,but you do NOT have to enter credit card info if you only want to view free content.

2)Some of the most popular free channels/apps are: YouTube,Pandora radio,The Roku Channel,Pluto TV,Tubi TV,Crackle,CBS News,NBC News,ABC,PBS, PBS KIds and many more.You can also find a free live stream of FOX News on YouTube by searching "Fox News Live" on YouTube.

3)Some of the most popular paid channels/apps are Netflix,Hulu,Amazon video,HBO Now,Vudu,Sling TV,Spectrum TV and Direct TV Now.

4)If you are looking for a bundle of channels of live TV to replace cable TV,check out Sling TV,Spectrum TV,Direct TV Now,Hulu,Pluto TV and Playstation Vue.All of these are paid services except for Pluto TV,which is free.

5)To find and add new channels on Roku,just press the Home button on the remote control,scroll down and select "Streaming Channels".There you will find thousands of channels/apps in many different categories and many of them are free.

My one gripe about Roku (and other streaming devices) is the lack of a fully functional web browser and I hope Roku will include web browsing on models in the near future.I have been surfing the web on the big screen for years and find it ridiculous when an internet connected TV device does not allow you to surf the internet and forces one to switch to yet another internet connected device to do so.
I am aware of screen mirroring function from smartphone/PC/tablet but find that a poor excuse to not include a web browser.Many people who type a lot of messages and/or emails like myself prefer typing on a wireless keyboard rather than a phone/tablet/remote control.

1）如果你需要在远离WiFi路由器的房间里通过WiFi连接ROKU，我推荐您购买Roku Streaming Stick PLUS或Roku Ultra.

2）如果你有一台4K电视，我推荐您使用Roku Ultra 或者是 Roku Streaming Stick PLUS.

3）如果使用声音搜索内容，您可以购买 Streaming Stick,Streaming Stick PLUS 或是Ultra.。这3种机型可以控制电视上的电源和音量。ROKU还有一个适用Android和iPhone iPad应用程序，它可以让你使用智能手机或者是平板电脑来控制任何一种RoKu设备，并可以使用你的手机/平板屏幕键盘或语音进行搜索。

4）如果你想要和有线以太网连接，用Roku Ultra.

5）如果你想连接到一个有RCA插口/ 复合音频插口/视频插口的老电视，你需要购买Express PLUS .

6）Express机型有个可用来操纵设备的遥控器，这是不同于其他ROKU机型的地方。

7）如果你只打算买一个RUKU设备，我推荐Roku Ultra。Ultra有很多其他的RUKU机型不具备的特性：

-玩电子游戏的游戏按钮

-远程查找丢失的遥控器

-有连接的以太网接口的线

-微型SD卡插槽

-USB端口

-夜听模式（这降低了过大的音量、爆破音，并且使过大的声音听起来细微舒适如耳语，非常有用！）

-遥控器上有听筒插口可以使你听声音时不会影响到别人。

对于那些以前没有使用过RoKu的人来说，这里有一些有用的提示：

1）使用RoKu没有月租费。有很多免费频道/应用程序提供免费电影，音乐和电视节目，有些人只使用RKU的免费频道，不用支付任何费用。如果您只希望查看免费内容您不必输入信用卡信息，您稍后可以随时添加信用卡信息到您的帐户以用于支付付费频道或者应用程序。如果您计划只查看免费内容，我建议在设置一个ROKU帐户之前，您先将设备激活。当您到达页面要输入信用卡信息时，一些浏览器会在底部显示“跳过，我稍后添加”选项。如果你没有看到这个选项，只需注销你的帐户，然后再重新登录就行。如果你在设备设置中跳过信用卡信息，你可能要为你的设备输入一个不同的激活代码。但如果你只想查看免费内容，就不必输入信用卡信息。

2）一些最流行的免费频道应用程序是：YouTube,Pandora radio,The Roku Channel,Pluto TV,Tubi TV,Crackle,CBS News,NBC News,ABC,PBS, PBS KIds 等.你还可以在YouTube上通过搜索“FOX News Live”在YouTube上找到免费的FOX News直播内容。

3）一些现在最受欢迎的付费频道应用是Netflix,Hulu,Amazon video,HBO Now,Vudu,Sling TV,Spectrum TV 和Direct TV.

4）如果你正在寻找一些电视频道来取代有线电视，那就去看看Sling TV,Spectrum TV,Direct TV Now,Hulu,Pluto TV 和Playstation Vue吧. 除了Pluto TV是免费的其他都需要付费。

 5）找到并在ROKU上添加新频道，只需按下遥控器上的按钮，向下滚动并选择“流媒体频道”。在那里你会发现在许多不同的目录，其中上千个频道和应用都是免费的。我对RoKu（以及其他流媒体设备）的不满就是缺少一个功能完备的Web浏览器，我希望Roku在不久的将来对机型增加网络浏览功能。我已经在大屏幕上冲浪了好几年，当发现连接电视设备的网络不允许你冲浪并且迫使你切换到另一个互联网连接设备时，我觉得这不能接受。当我知道智能手机/电脑/平板有屏幕镜像功能却没有Web浏览器，我觉得这是不能理解的。许多人更喜欢用无线键盘来打短信或电子邮件（比如我）而不是用手机/平板/遥控来做。

d recently they decided to go all digital so every TV in my home needs a cable box, which was a sudden surprise because we have 6 TV-s and we just did some remodeling recently and work extra hard to have the TV-s on the walls neatly. We did not wanted to have anything around them because the space is limited and after all what's the point to hang a TV on the wall nice and flat and then install a stupid cablebox somewhere sticking out 3 times more and collecting dust... I know whit long enough HDMI cables and RF remotes we could solve the problem after all nothing is impossible these days but everything is extra cost and again just because Spectrum cable decided to not to send signal in their antenna cables anymore... So in this upsetting situation our cable guy came and save us whit a great advice, to buy a ROKU stick and check it out. The reason why the ROKU, because this is the one and only media stick which supports the Spectrum cable app and we can watch all the channels what they provide and we are paying for it already! Of course ROKU supports others as well, like NETFLIX and even Google Play, so they don't discriminate anyone! I can't do anything just recommend this little stick to everyone! I was worried about not to be able to record my favorite shows anymore, but the cable guy said, don't worry, because everything is on-demand these days, even if it's not the same day, you might have to wait a day or two, but that's okay we can live with that. Just in case we still have a DVR cable box in our living room on the biggest TV for shows like the Superbowl... :)
Set up was very easy and the stick supports 2.4 or 5 GHz WiFi signals so the streaming is buffering free all the time. Our cable guy said the main reason why they go all digital, because in the old way, the TV signal eat up half of their bandwidth and this will help to speed up the internet as well so at the end it's a win-win situation for everyone. And the ROKU stick helps a lot, we don't have to rent a cable box from the cable company for $11.00 per piece per month... We got ours on Amazon but it's widely available of course and for $40.00 it will bring back their price under a few months compare with the renting! The available channels and contents are overwhelming, we still learning what is worth to watch, but the combination of Netflix and Spectrum and our own Google account, the possibilities are virtually endless. And if you can't find anything you can stream your family or vacation movies from your own phones and tablets. Or listen Pandora radio for example!
AWESOME AWESOME AWESOME!
Now I just have to buy 3 more for the kids rooms... Yay kids! :)
It is very rare when I write reviews but for a company who works this hard and created such a good little device they deserve it!
They even give away free HDMI extenders if your TV doesn't have a side HDMI port and you can't connect the ROKU stick in the back because your space is limited (which is the case with one of my TV-s)

设置很简单，设备支持2.4 或 5 GHz 的WiFi信号所以这个流媒体有大量的自由缓冲时间。伙计说，最主要的原因是他们都是数字的，原来的那种几乎是消耗了他们的电视信号带宽的一半，数字的将有助于加快互联网速度，这对每个人来说都是双赢。并且Roku流媒体播放器有很大的帮助，我们不需要花钱从有线公司买租金每月每个11美元的电缆盒…我们在亚马逊上买到的Roku，它当然比起来更合适，花$40.00带走它只相当于交了几个月的租金。现有的渠道和内容很多，我们还在探索哪些值得一看，但作为Netflix 和Spectrum 及我们自己的 Google的结合体，它的可能性是无止境的。如果你从自己的手机和平板电脑找不到任何可以播放家庭或度假时看的电影。听Pandora 电台作为例子试一试吧！

真的非常非常非常棒！！

现在我需要再为孩子们买3个放在房间里…孩子们！：）我很少写评论，但这家公司这么努力的创造了这么好的一个小装置，那是他们应得的！如果你的电视机没有HDMI端口，他们甚至会赠送给你免费的HDMI扩展器，否则的话你就不能在后面连接RoKu，因为你的空间是有限的（这就是我用TV-s的一个案例）。
