This kit was the last attempt before the scrapping of not even two year old camera. Had a bad spot on each picture I took with my Canon, and there's guarantee was it I of course only to be returned. Error. After Canon me "cleaned" had, it was worse. The camera had already written off internally, but then I came across this kit. Considering Hab long if I actually once again to invest 20 Euro, but I must say it has more than paid off. The kit is neatly packed and very easy to handle. Simply unpack, cleaning fluid carefully draufmachen (compact instructions inside, but you do not really need it), gently wipe over the sensor and the short leave all alone ... Habs let it dry for half an hour, do not know obs goes faster, wanted to be on the safe side. After the picture was almost perfect again. Can only recommend it, to me it really helped.
