At the end of 2006, we did our first Satisfaction Survey, thanks for partners' great support,

we got 75% feedback and we improved ourselves based on the results of the survey.

As a result, there were only 3 delays since 2007 and reduced the price by 10% because of expanding production and reducing cost. What is more, we finished the third great improvement on 3.5 -8mm varifocal lenses.
