## Customer Reviews

### ⭐⭐⭐⭐⭐ Ethernet adapter
*by P***S on 8 January 2024*

Works well with my Lenovo laptop and very fast download speeds. A reasonable price and quick delivery thanks.

### ⭐⭐⭐⭐⭐ Works well with the Yoga Slim 7
*by M***D on 9 February 2021*

Bought this for my Lenovo Yoga Slim 7 since it doesn't it have an ethernet port. It didn't install the correct drivers automatically, so I had to manually search for them from the Lenovo website. Adapter works perfectly after installing drivers.

### ⭐⭐ Fragile
*by F***R on 16 April 2025*

These are not at all rugged. Plugged into the router by the sofa and falling to the floor is not good for them. Expensive for something that cannot survive household use. Functionality excellent right up until its not.
