My sister bought this fpor me for Christmas as we have the same laptop and hers is starting to overheat a bit so she bought a fan for hers and found it to really reduce the problem. I wouldn't say my laptop is madly overheating lot but I never put it on a bed or anything and it does really get hot after a while on my lap.

When I first opened the fan I was a bit dubious as I'd had a different one before and while it helped, it was very noisy, bulky and my laptop fell off it unless I used it on a desk. This one plugs in easily (I was a bit worried that the USB wire wouldn't actually reach my USB port before I realised its just nicely held in the back in a curved way which you are meant to pull out to release a longer wire. I actually really like this feature as it is a good way to re-pack the wire away leaving it less messy and easier to store without damaging it. The USB powers the fan so there is no need for batteries/anything!

Once plugged in, the fan is surprisingly silent. You can hear it going but not loads louder than you can hear a normal laptop fan working. If you look at the fan you can see it going round and it is cool to the touch (All reassuring things!). This is great because I plan to mainly use it if I watch videos which make my computer work harder and I dont get disrupted by the noise of the fan!

The fan has a curved shape on side profile which you can't really see well on the DooYoo picture. It is also thicker at the back and thinner at the front giving it a raising, angular effect. This I think is meant to make it more comfortable on your lap. I don't really find it is more compfrtable though as it is still hard plastic but that might be just my fault, the curved shape and the angle doesn't really affect how well it works sitting on a table/desk though which is good.

There are also lots og grippy bits on this both to hold your computer to the fan and to hold the fan to the desk. One of the ones on top has started to come off for me allredy but I think it will just push back on. The grips do work well to stop your laptop slipping and sliding off it which i good when using it on your lap.

Size-wise it is good, it perfectly fits my laptop which is good. It also fits in my rucksack which i brill! I'd say its like the same size as an A4 lever arch file maybe. This makes it really portable for me and is great when I need/want to take it places which I have done already!

Colourwise, the box states that there is a range of colours available however my sister (who got this from Amazon) said she didn't get a choice at all. The back of the fan is a wierd greey which is slightly acidy. I dont hate it but it's not a colour I would actively choose!

Packaging wise mine came all lovingly wrapped in shiney paper with a bow, but underneath that (and probably if you buy one for yourself) it comes well protected in a cardboard sleeve/box type thing which has a piece missing enabling you to touch and really get a feel for the cooling pad.

The fan my sister bought was the larger version of this with speakers built into it which she says is good however due to the smallness of this one and the ease of portability, she's offered to swap and has allready borrowed my one a few times already! At £15 this is a worthwhile purchase if your laptop has the tendancy to overheat!
