Wired Ethernet - a Necessity

Works as intended. Not everything is WiFi so there is always a need for an ethernet connection.

It works as it should

What's there to say? It does what it is designed to do. I only wish the WiFi at the school where I worked was robust enough so as not to require using such devices. But, there you have it.

Stop Relying on Wi-Fi & Get This Adapter!

So happy to not be dependent on my Wi-Fi connection! My MS Teams, WebEx, and Zoom calls are so much more stable. I don't need to mute my video anymore. Very reliable. A very nice addition to my Lenovo Idea Pad 14. Very happy! And delivery went exactly as promised.

Small, lightweight, inexpensive, and functional

A necessity when reliable speed is needed and don't want to share wifi connection. Works as expected, no issues out of the box. Simple and straightforward.

Works better than the dock right away.

Works better than the dock right away. The dock never allowed me to get the DNS from my enterprise, so I was unable to log in the first time on a window session. This little devices solved that issue. I should have been provided with the laptop (Thinkpad X1 Gen3)

Plug and play

Just plug it in on a Windows 10 computer and it works perfectly. I wish the jack did not hang by a wire from the USB-C plug. I would like a molded USB-C plug with an Ethernet jack on the other end as a single unit.

Works perfectly

I purchased a generic brand adapter from Amazon and it would not keep a consistent connection to the network, so i decided to purchase this one directly from Lenovo and it works perfectly. It's smaller in size so it fits in my laptop bag easily. I highly recommend this adapter.

Cheap & works perfect

Purchased one of these to use with my iPad Pro 3rd Gen instead of my flaky wifi around the house & it simply plugs in & works with no need to do anything other than to connect a Ethernet cable to it. May only offer 100Mbps connection but that is more than fast enough to use on a home network (even if everything else is on gigabit connections). Cost me £8 from local CEX store in the UK in sealed Lenovo packaging with the warranty & compliance information leaflets.
