Have to order from Taiwan

they are sold in Germany as Sigma
wuite the same stuff abit more expensive but not a lot
totally unknown in France.....

Remember, it's cheap for a reason. It's like putting cheap tires on a nice car, why would you do it? Stay away from this junk, because you get only what you pay for.

I would not buy but 20 euro is cheap. I gues you get what you pay.
