I bought the 2GB version because it was much cheaper. It's my 3rd tv box and I have to admit that finally everything runs so fast. Although I initially got it to play Ps1 games more comfortably, I see that it's worth getting it even for Kodi because everything becomes more user-friendly. I dare to say that now I'm starting to explore Kodi because until now I was bored waiting. The downside is the incompatibility with teamviewer qs.
The 3GB version is worth it just because the ROM has a very large size. With the 2GB RAM and loading the same apps compared to the other 2 devices that also have 2GB RAM, I end up with at least 400MB less RAM. Nevertheless, besides the Ps1 games, I have installed 5 Kodi forks and it works without any signs of overload.
P.S.: The tv box is not suitable for Netflix users who want to use the Netflix app (as is the case with the majority of tv boxes). The latest suitable version is 6.26 and the maximum resolution is 960x540p.

The first one I bought broke for some reason within 5 months, it was under warranty and the store was extremely helpful and replaced it with a new one. I have been using it daily for a year now and it works perfectly. Thank God.

The first few days it was good. Then it started freezing and in order to wake it up from sleep mode, you have to unplug it. It broke after 3 months.

Terrible experience and a waste of money. It constantly freezes, the remote control doesn't work beyond 1 meter, and in just 4 hours since I bought it, it has crashed about 20 times. Simply tragic...

I never managed to connect to the internet with this machine using a cable, only wirelessly...
At the store service where I returned it, it was supposed to be working fine.
In the past three months, it started freezing without being overloaded with too many programs.
To restart it, it was impossible to shut it down from the remote control, so I had to unplug the power cable.

It lasted me a year and something, suddenly it started not to open but with some restart it would open until now it completely crashed. Maybe because I didn't close it properly, I don't know. I bought it from China for 50€. It's not worth it for 80€. You definitely need a mouse and keyboard because the controller requires patience! Overall, it's a decent machine for popcorn, Netflix, etc. but even those would sometimes freeze. I believe you can do the same job with a cheaper one.

I have changed three machines so far because they all have some issue.... one didn't give a signal to the TV, the other one's sensor only went halfway up the screen, the other one didn't turn on....... ummm I threw it against the wall and stopped running to replace it.... wasted money

I bought it for my vacation home mainly to view files from the USB stick. The TV does not have a media center. The remote control is very inadequate. It's almost impossible to use it without a keyboard. I bought one with Bluetooth and it connected relatively difficultly. Consequently, it is slow in its responses and freezes many times. I even struggle to turn it on and off (with the remote control). For some reason, when it turns on, it automatically plays a specific video without me giving it such a command, and I have to stop it every time. I'm not thrilled with it for its price.

I don't have much experience with TV boxes, but after researching those that play up to 100€, I concluded that this was the best one and I bought it.
Fortunately, it doesn't lag at all, the menu is easy, it already has pre-installed Playstore, Netflix, YouTube, etc., and so far I haven't complained about anything.
The only negative thing is the remote control, but I bought another one for 10€ with a trackpad and keyboard, and I'm a boss.
It's definitely worth it, I would say

I have bought it here for 2 months, on January 10, 2018, for 70 euros from China. The power supply is not faulty, everything is fine. I have installed Kodi and it works perfectly

I bought it on 26/02/18, used it for a day and the impressions are very good so far. The only problem I encountered is that VLC does not recognize the subtitles, but it was solved with BSP. The remote control is for basic things, like I imagine all of them are.

Along with the GT1 Ultimate, it is the most popular media box.
Excellent in all aspects (especially in the version with Nougat).
Keep in mind the purchase of a power supply along with the purchase, as some batches have issues and occasionally bring along the player itself

It keeps freezing constantly, displaying multiple colors on the screen, and making a noise like zzzzzzzz... I was told it might be the power supply, so I changed it, but it still does the same thing.

Unfortunately, it has a problem with the power supply. Its motherboard got burned. They replaced it at the store with another one which, although I have used it for a total of 6-8 hours, caused crashes and a strange sound as if the hard drive had been hit. Otherwise, it is a very fast tool, plays movies, surfs the internet, and plays 60% of the games I installed.

One of the two giants of our era's TV boxes!!
