This was a feature i decided to add into my recent custom build PC, when i looked at the price it almost seemed a no brainer, for around £10 you can pick one of these up and they're so simple to just put in your computer and plug in and you're done.
Usefulness. If like me you're someone who is keen on taking photos/videos you will know that you have to regularly keep uploading the images and videos to your computer so your memory card / stick doesn't get too full up. Here's where this comes in handy. How many times have you sat down at your computer ready to take everything off your camera and put it in folders and realise you cannot remember where you put the sync cable, but then you remember you bought one of those multi readers that you can plug into the computer via USB, then you realise you are clueless as to where that is also. Then you can have this for only £10 which will do almost all if not all as far as I'm aware memory cards and memory sticks, it even provides you with an extra USB port.
How it fits. Looking at it for those not very computer literate it can look quite odd and you may wonder how this may fit, it is similar to a CD drive in that it just slots into the front of the computer, you can take one of the plain black/grey dependent on PC colour, panels off and this slides in. Then all you have to do is plug in power and connect it to the motherboard and you're ready to go.
Design. The design of the card reader is fairly simple, it's pretty much just plain black so looks really good on a black computer like mine but on a grey computer it may look a little out of place. It has a little yellow light that you can see in the image next to the slot on the top left that glows as long as the ports are operational. It also lists what type of ports they are next to them to avoid error or confusion.
In conclusion if you're looking for a multi card reader or even just one then this is a very good choice, it's cheap, you know it's never going to get lost or be misplaced and it means you should be able to use it with other cards should you change camera or device.
