Kingbox K3 OTT Box


The Kingbox K3 is our first pick for our Android TV box. The unboxing experience has been one of the most satisfying ones yet,

we get many accessories with the Kingbox K3. These accessories include a mini keyboard, Remote control, HDMI cable, and a power brick. Many other TV boxes cannot be said as many do not even include an HDMI cable. 

The Kingbox k3 has an Octa-Core processor from Amlogic, paired with 2 gigabytes of DDR3 Ram and 16 GB of storage.

The Antutu benchmark comes back with a score of 49000, which is more than enough for your content consumption; however, it does struggle while playing the latest and greatest android titles. 

The Operating system of the Kingbox k3 is Android 7.1, which has aged a little bit in 2021; however, it still works very well, and most of the apps on the Playstore still support it very well. 

On the connectivity front, we can connect to the Internet using a dual-band Wifi connection which will let you connect to all 2.4 GHz and 5 GHz bands. Bluetooth 4.0 connectivity is also given in this device, connecting Bluetooth speakers or Bluetooth game controllers to your Kingbox K3.

The Kingbox K3 is not a Powerhouse of a machine when speaking strictly about its specifications. However, it is a great content consumption machine.

You can quickly watch your favorite TV shows and movies in full HD or 4K with ease. During my usage of the Kingbox K3, I never noticed a single frame drop when I cranked the quality up to 4K 60 FPS. 

The included keyboard is also a great inclusion in the box as it very easily lets you navigate the menus and search for the things you want to watch.

It can also be used as a game controller if you want to play games on your Kingbox K3. However, the included remote is nothing to write home about; however, it works as it should.

All in all, the Kingbox K3 is a great entry-level machine for those who are buying an OTT box for the very first time and want to experience Internet content on their television directly.


  • A Lot of accessories are included in the box, like a mini keyboard, HDMI Cable, etc.
  • Supports 4K with no frame drops.
  • Ability to use social media and other Android Applications.
  • Dual-Band WiFi Connectivity.
  • Easy to set up and use.


  • The device is underpowered.
  • Remote quality is not good.


So, now moving on to the price, does the Kingbox K3 justifies its retail price? Well, at first glance, I would have to say. No, however, there are times when you can buy the Kingbox k3 for half its sale price.

That is when you should swoop in and grab yourself a Kingbox k3. If you manage to do that, I believe you will get a lot of bang for your buck and enjoy your experience with the Kingbox K3.

At first glance, the Formuler Z8 4K UHD Android OTT TV Box is a sleek-looking device that strangely resembles a WiFi router. However, looks can be deceiving because this is one of the best entry-level OTT TV Boxes available on the market.

The unboxing experience is as straightforward as it can get. We find the device, along with a pleasant feeling remote, a power plug, and 2 x AA batteries for the remote.

Once you set up the Android Box using the HDMI cable, e you are greeted by the quick start menu where you need to sign in to your google account because Android powers this machine; once you are done doing that, you find an excellent-looking User Interface where you can start watching whatever content your heart desires.

SHIELD TV Pro OTT Streaming Media Player


You might have heard of NVIDIA if you are a gamer because of their flagship graphical processors; however, they also create Flagship level Android OTT Boxes.

The Nvidia Shield Pro is a refresh of the 2017 NVIDIA Shield. The Shield Pro is updated with the Tegra X1+ processor along with a 256-bit NVIDIA GPU. This complete self-reliance of components makes it so that they have created the best OTT Android Box available in the market.

The Unboxing experience is also great with the Shield Pro. Opening the green and white box, you get the first layer where the Shield Pro unit and the Remote are resting.

The remote of the Shield Pro is very unusually designed like a triangle; however, this makes it very ergonomically friendly to hold. Taking the first layer out, we discover a second layer where we find the power brick along with the quick start guide. 

The Shield Pro has a very sleek, unibody design. The green led accent makes it feel like a product out from NVIDIA. We have 2 USB 3.0 ports on the back, which enable higher transfer speeds. We also have an Ethernet port, an HDMI port, and a power port.

Turning the device on, we have to sign on to our Google and NVIDIA accounts. Once the setup is finished, we find a very intuitive and easy-to-use interface with all the media consumption apps we would need.

The Tegra X1+ is a powerhouse of a Chip with an Antutu score of over 256000, which makes it the best in class. The 3 Gigabytes of Ram and 16 Gigabytes of storage are also a staple of the NVIDIA Shield Pro.

So do all the features justify the price? To that, I will be saying a resounding Yes as these features are worth it.

No other OTT box allows you to play AAA games using cloud computing or make your content look better than it already is natively. So if you are looking for the best OTT Android TV Box, then the NVIDIA Shield will be the best for you.

Minix Neo U9-H


The Minix Neo U9-H is our last pick for the best OTT Android TV boxes available on the market right now. The unboxing experience of the Neo U9-H is very straightforward. You get the device along with the power cable and the remote. No extra accessories are included inside the Box. 

Designwise, the Minix Neo U9-H, like the Formuler Z8, looks like a small WiFi router. However, this is what makes me like this device so much.

It is small and discrete and does not need much space. We also have a lot of ports on the Minix Neo U9-H. We get 3 USB 2.0 ports, an IR receiver, HDMI Port, Headphone and mic jack, Ethernet Port, and a MicroSD card slot.

The device is being powered out of the box by Android 6.0, which is upgradable to Android 7.1. However, this feels very dated in 2021, but it still can support most of the applications you need for content consumption.

The processor of the Neo is an Octa-Core Cortex A53 Chip which is paired with the Mali-820MP3 GPU. We also have 2GB DDR3 Ram and 16 GB of storage. 

Connecting the device to the Television, we get a quick start screen where we have to log in to our Gmail accounts, after which a very user-friendly Interface welcomes us.

We have all the applications that we need like Netflix, Hulu, Youtube, and So on. Watching 4K content on the Neo U9 is hassle-free, and it does not lag or stutter.

On the connectivity side of things, we can use Ethernet and WiFi to connect to the Internet. We also have Bluetooth 4.1 here, which lets you connect any BlueTooth speaker you may have to the device. 

The Minix Neo U9-H is an excellent device that allows you to watch your favorite content with ease in 4K quality. You also have support for all the social media apps and games; however, you should not expect a gaming powerhouse and keep your expectations moderate when gaming.


  • Good 4K media consumption machine.
  • It has an audio jack,
  • Ethernet port and WiFi.
  • Supports a lot of video and audio formats.
  • 3 USB 2.0 ports for connecting external media storage devices.


  • Slightly underpowered.
  • Android version 6.0 is almost outdated.
  • HDMI is not included.


The Minix Neo is a great device that will cater to all your media consumption needs; however, we also need to know whether or not the money you are going to pay for it is worth the actual price of entry. To that, I would like to say that it depends.

If you can get this device in a sale, then you are very likely to get your bang for the buck. However, if you are going to pay retail for it, skip it and buy another product from this list.


Well, here was our review of the best Android OTT box on the Market. So as promised earlier, here are my thoughts condensed in conclusion.

The Kingbox K3 and the Minix Neo U90H are great products on their own however their price on the retail market is not worth it due to their outdated Android Versions.

If you can get them in a sale, then you will get your money’s worth. 

The Formuler Z8 is a great mid-range OTT TV box, and if you are looking for something that works well and lets you watch 4K content for a reasonable price, then you will not go wrong here.

The Amazon Firestick 4K is one of the best and most feature-rich OTT Android Boxe I have in our arsenal, and it justifies its price. However, the low storage and the absence of the google play store might be a deal-breaker for some people.

The clear winner and the best OTT Android TV Box with the best remote have to go to the NVIDIA Shield. It does everything and more you would want from an Android TV box, and the performance of the device fully justifies its price.

I would have liked a little more ram here on this device for future-proofing; however, I can not say that I have any regrets about buying this device.
