Roku Ultra player retails at $99. However, deals are often on the run where you can get it as low as $79 and add-on bundle deals to get earphones and Alexa for a much cheaper price. Roku ultra features a quad-core processor and it’s believed to load faster than any of there other players on the list. It supports 4K and HD streaming and it’s especially great if you’re users who stream heavily on 4K. The dual-band wireless connection is great for users who stream with or without an ethernet port connection.


  • – Support extra storage space
    – Compatible with Ethernet connection
    – Voice remote control support
    – 4K playback with faster channel load time


  • – Basic design
    – Pricer

It is one of the best flagship media streaming players offered by the company. Roku Ultra has been constantly updated with new software, improved system performance, and the option to customize the remote control. However, it uses a more traditional streaming box design and has a compact size. It delivers 4K HDR playback, support for extra storage, and a voice remote with a headphone jack.

It supports storage expansion through a microSD card or USB flash drive. You can store photos, music, and movies into these devices and plug them in to stream your media to your TV. It is the sole Roku player that is compatible with a wired Ethernet connection, which is a suitable feature for users who don’t have a Wi-Fi connection at home. This supports a voice remote feature as a bonus, which other Roku remotes don’t have—a handy headphone jack for listening. Though some might encounter some errors that can cause the Roku remote not work well, here are the fixes you can refer to. 

Our Verdict

Roku Express is great if you in search of something easy to set up and you’re ready to settle down with just HD playback. It’s the cheapest in the range but it does the job. Though it’s compact and small, the performance is outstanding and the load time is quick too.


  • – Affordable
    – Compact and sleek design
    – Easy to set up


  • – Does not support 4K playback
    – Wireless support only

With basic HD playback and Wi-Fi connection, this is the most affordable and simplest Roku unit. The entry-level version of this type is Roku’s most inexpensive media-streaming player, and it’s a perfect option for users who prefer simplicity in HD streaming solution. It connects to the internet through Wi-Fi and is developed to rest on a stand.

The small box is so dense that it is actually tinier than the remote included in the package. For simplified setup, it only has two connections, one for power and one for HDMI that connects to your TV.

For Wi-Fi integration, this type of device utilizes 802.11bgn single-band wireless. This is an older wireless protocol compared to some versions used on some players. The drawback is it doesn’t support a wired Ethernet capability.

This is the most basic media player that Roku has ever made and is still a worthy purchase if you don’t have a 4K TV and don’t require 4K streaming.


Our Verdict

Users of Roku Premiere can stream almost any channels on the platform. Whether it’s Disney+, Hulu, or Netflix it’s all available. This device is built-in with Wi-Fi support and it features stunning clarity when you’re streaming in HD, 4K, and HDR. What’s great about this as compared to the others is it optimize the TV picture quality for better and sharper resolution. It’s easy to set up and it also comes with premium HDMI cables for every purchase. 


  • – Affordable and money to quality assured
    – Fast updates


  • – Does not support voice remote
    – Remote feels sluggish and unresponsive

It is an inexpensive budget streaming player for users who want 4K HDR support. Similar to the Roku Express, this is an ultra-dense streaming box. Aside from the streaming of full HD content, this type steps up things to the next level with support for 4K streaming that is four times the resolution of full HD.

It also delivers HDR10 support from compatible apps such as Disney Plus and Netflix. TV shows and movies with HDR are capable of offering enhanced colors and contrasts on compatible 4K HDR TVs and home theaters.

Similar to the majority of Roku players, it is Wi-Fi-only and isn’t compatible with a wired Ethernet connection to the internet. It is also integrated with the same 802.11bgn single-band wireless capability as the Roku Express instead of the 802.11ac MIMO dual-band wireless functionalities integrated into Roku’s more expensive units.


  • – Voice control remote
    – Supports 4K, HD, HDR


  • – Nothing much stood out from Roku Premiere

The Roku Premiere and Premiere+ are nearly identical streaming devices. However, the Premiere+ distinguished itself with the voice remote control. As for the price difference, you’ll get a sturdier remote that supports Bluetooth and inferior remote. So, for almost double the price from the premiere, we weren’t sure if it’s worth keeping those hassles away.


Our Verdict

What’s differentiates Roku Streaming Stick than the rest is doesn’t come in small boxes but a stick that plugs into your HDMI port mimicking the approach of a Chromecast and Firestick. However, this Roku Stick comes with remote control, unlike its competitors. It supports HD, 4K, and HDR with a longer range wireless receiver. It’s compact yet powerful with up to 4x the wireless range that allows you to stream comfortably even if you’re far away from your router. Its remote also supports voice control. The best selling point for Roku Stick is it’s portable and great to travel with.


  • – Good quality to price
    – Portable
    – Supports long-range wireless
    – Extensive free movie channel


  • – Voice control doesn’t work well with other streaming devices

If you’re looking for a compact device, the Roku Streaming Stick is almost like a USB flash drive. It is similar to the Roku Premiere; however, instead of plugging into a USB port, you plug it directly into your home theater’s or TV’s available HDMI port. It has a built-in Wi-Fi for connection to a broadband router. It has a maximum of 4K HDR streaming from supported apps for enhanced contrast, color, and detail.

Unlike Roku’s inexpensive units, this also highlights the newer 802.11ac MIMO dual-band wireless protocol, which provides you with a more stable and reliable internet connection. It also comes with a voice remote so you can browse for content using spoken or voice-over commands.

Also, Roku has developed a standard Streaming Stick model aside from the Streaming Stick+. This model is similar to the Streaming Stick+, except it doesn’t come with 4K HDR streaming support. Both models have the same prices, but the Streaming Stick+ is obviously the newer, more advanced version.

This is a comprehensive all-in-one solution with the operating system already configured in the TV itself, eliminating the need for a stick or external device to access content from the internet. Furthermore, this device connects your broadband router either through an Ethernet connection or Wi-Fi. TV companies that integrate Roku TVs in their product listings include TCL, Sharp, Insignia, Hitachi, and Hisense. It comes in numerous screen sizes, including 720p, 1080p, and 4K Ultra HD versions.

How Does Roku Works?

Whether you purchase a Roku TV, Roku-enabled soundbar, or Roku player, the movie streaming experience will be the same. All its models require an internet connection. Some units offer you the option of using an Ethernet cable for a wired connection to your router or modem; however, all these will work with Wi-Fi connection too. Once you have already completed the setup of your Roku device, including the free registration of an account, you can start your seamless media streaming experience.


How to Navigate the Home Screen

The first module you will see after the initial configuration is the home screen. It has a main menu on the left side and a series of big graphic rectangles on the right positioned in an easy-to-read grid aesthetic. These rectangles, which will display items such as YouTube, BBC iPlayer, Hulu, Amazon Prime Video, and Netflix, are known as channels. Channels are similar to the apps on your mobile devices. But because Roku is media-centric, it considers them as channels because you are streaming content from them.


How to Navigate a Channel

To stream a specific content on a channel, simply use the remote and locate your preferred channel and press “OK.”  Remote controls are also included in the package when you purchase a specific device. The channel will immediately open; however, if it’s a subscription-based channel such as Netflix, you will be prompted to sign in or register for a new account. That said, registering for a new account will require you to use a PC, tablet, or a smartphone for one instance only. Once you already have an account, you don’t need to use these devices every time you access Roku.

If you want to stream another channel or navigate to the home screen, simply press the home button on the remote. Choosing and opening channels are the principles of Roku, but there’s definitely more stuff you can do on your device.
