On 20/07/2019, the cable that connects the device to the laptop broke. Low cost indeed, but minus one star.
The 5 stars refer to what it offers in combination with the purchase price, which is below €9.
The noise is low and not bothersome. The dimensions are ideal for a 15.6' screen and the weight is minimal. It is perfect for a low-demand laptop. Of course, more demanding users should seek higher quality and certainly more expensive solutions.
