Which is a good network set-top box, 2017 four must-see shopping skills
There are dozens of brands in the network set-top box market, with prices ranging from tens to hundreds of yuan. This wide variety makes it challenging for users to choose the right one. Many people who aren’t familiar with set-top boxes assume that cheaper options are sufficient and end up buying low-cost models. However, these cheap boxes often fail after a short period. At first, they work smoothly, but after two months or so, they start to freeze, flicker, and crash—making them unusable. Online complaints about this issue are common. In this article, we’ll share four key tips for buying affordable set-top boxes, helping you avoid the pitfalls of low-priced products and find a truly useful and reliable device.
1. **Quality Matters – Choose a Reliable Brand**
Set-top boxes priced below 200 yuan are typically of poor quality. Many independent reviews have shown that these devices cut corners on materials and components. On the other hand, high-quality boxes costing over 300 yuan usually use imported parts like Samsung, Kingston, Toshiba, or Zhengji. These materials ensure smoother performance, longer lifespan, and fewer malfunctions.
2. **Poor Cooling Systems Lead to Overheating**
Low-cost set-top boxes often suffer from inadequate heat dissipation, which can cause frequent crashes due to overheating. Most budget models are mass-produced without proper thermal design. Upgrading their cooling systems would significantly increase costs, so manufacturers tend to stick with basic designs, leading to performance issues over time.
3. **Low-End Boxes May Automatically Uninstall Apps**
Some budget boxes come with pre-installed software that automatically uninstalls apps in the background, potentially turning the device into a "brick." Not only are these boxes difficult to customize, but they also lack user-friendly app management. High-quality boxes, on the other hand, run on stable operating systems like Android, allowing users to install and manage apps without worrying about unwanted removals.
4. **Mature Technology Ensures Smooth Performance**
The main purpose of a network set-top box is to stream video content. Low-cost models often struggle with buffering due to outdated technology. When problems arise, there’s usually no dedicated support team to help. In contrast, high-end boxes are optimized for popular streaming platforms, offering strong decoding capabilities and smooth playback even with large volumes of video content.
Here are some top recommendations for popular network set-top boxes on the market:
