I tried several systems including systems with wet pad and also the PENTAX kit which is based on the same principle as the Eyelead. The wet pad cost a arm each use, lenspen system is not bad but still laborious and magnifying glass provided does not see much and the PENTAX kit is not quite "sticky" to properly remove dust, it need to try several times and we have the impression that move dust removal. Eyelead with the kit, in a passage, I had removed 95% of the dust and the second passage there remained some tiny dust in the corners visible only to f22. I highly recommend this product effective and very economical final.
