I've tried that one too, and found it very cumbersome
to use. The instructions say to be sure NOT to get
any on the edges of the lens surround (for good
reason), which means in essence you're not cleaning
the very edge of the lens element. If you do get it
on the lens surround, it can be very difficult to get
off. I found it a lot more trouble than it's worth.
Also, don't use it on plastic elements (and the rear
elements of some of Canon's consumer lenses are
plastic). It will ruin them.
