At first,I don't know reza has seen what product of me
But I must say I am very glad to hear reza know me from my product


Steve,
It depends to kind of trade
Sometimes the product is for a company,And the Priviege is for that company
And sometimes the product is for a company,but the company is responded to selling that product,the guaranty,... is for designer,and sometimes i design a product and i sell it to a electronic shop in tehran and this shop give it out in other cities like Shiraz
In two later case i put my name,email and phone in the product
There is a key "Admin",when it pressed
My profile with special effect appear in screen
I think it is good way
Because not only i am available for the customer
to supporting but also it is good propaganda for next offers
Isn't it steve?

Best Wishes
Mehdi
