Functioning ok - Swabs but wider than the sensor and Kit comparatively expensive

1) The cleaning liquid is VERY low. Just be aware directly. 5ml sounds much. The joke, however: The company has filled the bottle only to 50%. For this two star deduction, because that's really nasty and not customer friendly. If it is nevertheless perfectly ordinary to methanol, if I'm not mistaken.

2) Sad but true: The supplied Swabs are wider than the sensor of both Canon 50D and Canon 40D ... It can not therefore in a train from left to right wipe over the sensor, but has to 2x as lawn mowing over it. Awkward!

I paid 30 euros for the set. A couple of years I'll make do with it, 12 cleanings should be feasible, I hope. And then there's hopefully provider in the market that offer a little more than Eyelead. I find it somewhat outrageous to charge 30 euros for 12 plastic sticks and a thimble. But people are willing to pay it, and many alternatives are not.

A tip: Blast First the mirror box thoroughly, using a blower. And only when the mirror box and the focusing screen are clean, goes for cleaning. Otherwise you have afterwards fortiori back dirt on the sensor!
