Very good. the only downside is it doesn’t support gif. only static images. you need to buy 5.0 and above sizes for video/giff

I really liked it. As for the software, I preferred AIDA64. It has much more information.

excellent product

Communication with the store quite complicated, robotic automatic responses, in short... very unpleasant! !! ! 😡🤬

good product for monitoring

Excellent fabric! I recommend it.

Top.👏🏾👏🏾👍🏾

It works perfectly, the base is great and solves the problem of where to leave it, it consumes little energy, I placed it on a HUB connected to the laptop and it worked perfectly. I recommend it.

3.5-Inch USB-C Mini Secondary Monitor for PC Performance Stats

It's actually quite fun, it even helps you monitor your computer, although I don't know if the software you download, like the Chinese version, also checks your data, but for now I really like it and the screen is very clear.

Arrived on time, I recommend the product.

The screen works as intended, you can connect it with a usb cable externally or with a 9 pins directly to the motherboard, you can find themes online too as the one i'm using.
