Counterfeit products have become a serious concern for
ZHICHENG. Counterfeit products are hurting not only our
business, but also authorized distributor's benefits,
and above all, users are the number one victim. Counterfeit
products are often sold at very low price, but of inferior
quality and performance, and may even cause safety problems
including the risk of fire hazards. Sometimes it is difficult
to identify counterfeit products in the market because
some of them look almost identical to genuine ZHICHENG
products. Please be advised that we are not responsible,
will not be liable for any damage or loss resulting from
the use of counterfeit products and will not provide any
technical support of counterfeit products.
products get a renewed CE Mark approval
from DNV (Det Norske Veritas), which allows
its products to be marketed in EU member
countries as well as many other countries
that recognize CE.
