## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy installation works perfect on windows 10
*by D***A on 19 December 2020*

Easy to fit and worked out of the box no issues on windows 10 with a dell motherboard.

### ⭐ Waste of money
*by D***L on 7 March 2024*

Windows 10 doesn't recognise it, who has a cd rom these days to use the provided cd to install the drivers, can't find the driver anywhere, it is a waste of £20 Update Seller provided a refund quickly

### ⭐ Don't waste your money on this rubbish
*by B***N on 3 January 2021*

Fitted this card, switched PC on, and its been stuck at the windows logo for a couple of hours now. It says on the box that it supports multiple USB 3.0 USB 2.0 devices. And each USB port supplies max 5v power to USB device. This is rather odd, given that it's an RS232 serial port card. !?
