I do not even remember how this one got into our household it just was there one day. Probably the work of my father... We got the 140g one and it comes in a cup, I have looked it up on the internet and found out that you can purchase this in a 75g bag, 140g cup, 145g pop-up cup (as on the picture provided by Dooyoo) and in a 500g and 1kg bucket. There are 3 different kinds of Cyber clean, one for home and office (the yellow one, the one I have) one for the car and one for the shoes. The one I have now costs £6.76 on Amazon.co.uk, the one on the picture £6.85. It is used for "desktop equipment" - keyboards, phones, cameras, consoles... I use it on the keyboard mainly and to clean the phone, well the few keys it has.

As you open the cup (or whatever shape of packaging you choose) you are greeted by lemony rubbery stench but as the thing gets some air the stench becomes a little bit less strong. As you use it some of the scent stays on your hands so you will have to wash up after the use if you do not want to be "stinky". It also leaves a subtle stench on the surface for a day or two - but you have to stick your nose to it to smell it.

It is a soft gooey blob that is a little bit grouse to touch for me personally, it reminds me of some toys I liked when I was a child, those weird balls you would throw and they would stick to everything and you could stretch them - well something I liked as a child but find disgusting now.

To use it you grab it and press it (do not rub it!) on the surface you want to clean and remove it - the dust and apparently germs (it is supposed to kill up to 80% of them) but I do not have the expertises to test that - although I could give my microscope a run for the money one day - not sure if I would ever want to touch my keyboard ever again after seeing everything that is lurking there.

I have to say it works perfectly on my mobile phone it removes all the dust that gets stuck under the edges of keys. It does not leave any stains nor are the keys sticky or greasy after use - they are just plainly clean!

As far as the keyboard goes - it does a better job than a mini vacuum cleaner I used to have but it still does not collect all the dust under the keys - the keys themselves are really clean and spaces between them too, it even cleans some of the space under the keys - but some dust stays - this might also be different with different keyboards - but it still cleans a large portion of the keyboard vacuum cleaner would not.

Opposed to a vacuum cleaner this sort of cleaning is times and times faster, press - pull, press - pull and a few times more and you are done in under a minute.

Now where does the dirt go you might ask... Well the bloob consumes it, yes all the dirt stays in the blob forever! Not a nice sight, especially if there are larger chunks in it. It over time (as it gets dirtier and dirtier) gradually changes the colour from lively yellow to dirty yellow - and when it hits a certain shade of dirty yellow (colour indicator is on the cup/bucket...) it is time to throw this one away and get yourself a new one.

When does this time come is really hard to say - we have this one at our home for about half a year and use it moderately - it is still more on the bright side. It all depends on how much you use it but I reckon that it does not go to waste too fast.

After it's served it's purpose and it is time to get rid of the thing there is another thing you should know about this product it is biodegradable! By the looks of the thing I would never imagine it but it seems it is. Another good thing with this product. Not a bad product all in all!

The reason I gave this one a 4 star out 5 is because of it's odour only.
