### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    An easy way to add some USB 3.0 ports and extend your laptop's life
  

*by D***. on Reviewed in the United Kingdom on 8 February 2023*

It came with a driver on a disk, but I read somewhere that it's for Win 10 and up.  I needed it for Win 7 so I found a driver online.When I plugged a USB 3 device to it, Windows said to plug it to USB 3 port instead of USB 2, but that's just Windows being confused.  I tested the Expresscard's transfer speed vs the laptops 2.0, and the Expresscard was 3x faster.It's much more convenient/cheaper using this Expresscard (if your laptop has a slot for it) than using a powered, external, USB hub.Delivery from China took a while, but it wasn't too bad (few weeks) vs what I'm used to (few months)I've been using it for a few weeks now.  I've had no problems so far.

    Works well in Lenovo ThankPad X201 with Ubuntu 22.04
  

*by P***B on Reviewed in the United Kingdom on 5 July 2023*

Plugged this card into my faithful old Lenovo ThinkPad X201 and immediately have 3 more USB ports and they are USB 3.0! No driver install or configuration required with Ubuntu 22.04.Tested with a 2.5" SSD and a USB3-to-SATA adapter. When plugged into a USB 2.0 port on the X201, I get 32MB/s transfer speed. When plugged into a USB 3.0 port on this adapter card, I get 180~200MB/s. Not as fast as the same SSD & Adapter on the USB 3.0 ports on my desktop PC, but still hugely better than with USB 2.0.The card does get somewhat warm when inserted for some time, even with nothing connected, so I guess it will reduce battery life. Gets very warm when in use with USB devices plugged into it. So I suggest keeping the adapter in your laptop bag and only inserting it when you need to use it.

    Rubbish
  

*by S***N on Reviewed in the United Kingdom on 22 June 2023*

Total rubbish. Just got hot and didn’t work. It’s so bad that I received a refund and told not to send it back.  Don’t be fooled by the one star. I wasn’t able to give it no stars.
