It would go for 5 stars, as it has all the games of my pre-adolescence and adolescence. Of course, with this specific amount of money, it's logical to have some problems.
A) Many titles that you have to add to favorites, otherwise you get lost.
B) As a friend mentioned, when powered by my USB, it would cause a power outage in the house, so I plugged it into a mobile power supply and directly into the power outlet.
C) The controllers would lose contact with the stick several times during the game.
D) Unfortunately, after 4 nights of use and <15 hours of recovery of cherished memories, it gets stuck on loading when connected

And f@#king amazing tools... We became 10-year-olds again without the need to spend a dime... And the best part is that the kids stopped being glued to their tablets...

Positives:
- Price.
- Size and portability.
- Variety of games.
- Ability to add games to the SD card.

Negatives:
- The SD card is very slow and of poor quality, resulting in game lists freezing and search issues.
- Does not work with controllers other than its own.

Tips:
- Clone the device's SD card because it is the first thing that will break down due to the poor quality of the card and the fact that the device does not have a shutdown option, so it is certain that bad sectors will occur at some point.
- Provide 5V power from a mobile charger and not from the TV's USB port. The power from the TV's port may not be enough to power the device and the joystick adapter, and it will also prevent sudden power interruptions and damage to the SD card.

For its price, it's pretty good. The only downside is that the games related to the PS1 freeze to the point where you can't play.

Flawless, many games, you can add more from the internet (Roms) and they play, they just don't appear on the list, you can find them by searching for files.

It works perfectly, I bought it for my 11 and 9-year-old children, who are thrilled with it. It connects easily and they haven't encountered any problems so far with its use. It's worth buying

I tried it for my son, a very good choice.
The truth is that I play with him sometimes and other times alone, what can I say, it reminded me of my childhood when we used to run to the arcades (that's what we called the shops that had electronic games for us to play). We have spent a lot of coins in them, and now with just a flash drive, you can play all day!

Good overall. It has many "junk" games inside and it takes many hours to delete the useless games.
It also has serious shortcomings in terms of games compared to the Mame I had on my computer.
The good thing was that I adapted the joysticks to the computer and it's better that way!
