Actually 4 stars if not for the "felt pen" ...

The or the items are processed reasonably well for the money. For fast rough cleaning the set enough basically. The blower has sufficient force to remove coarse dust particles, the cloth helps unsightly fingerprints on the display and remove the brush can remove dust in spaces. One must, of course, but no brand quality expect the price / performance ratio entitled actually well-intentioned 3.5 to 4 star.
Why then so but only 2 stars?

As a previous reviewer has already written, colors of "cleaning tool" extremely off! On a piece of paper you can use it almost as a marker. I find that totally unacceptable, since you can pretty much be dirty lens hereby.
Have this "sharpie" problem for my research but unfortunately many of cleaning pens from other brands. Also be found in the reviews of the Lenspen for example, Hama many customers opinions who complain about this lack.

Conclusion: I will keep the set as it is (in part) for the rough cleaning for the price ok. The felt side of the Lenspen I will, however, have never been used on a lens and I therefore look for alternatives. Next time more money is spent but then, after you clean lenses and other accessories are not cheap.
