Hello , this is Steven from Blue Sky Co . May I speak to Mr . James ?   Speaking .   Excuse my troubling you . You purchased our products last year and now I am following up to find out about their workings . Are they still in good condition now ?   Yeah , exactly ! I bought them last year . En ... at present , they are still in good state .   That's it ! All of them have first-class quality and performance . Besides , we adopt advanced technology . Now we have developed new products . They are much better than what you have bought .   Your company is developing so fast . Maybe later on I will plan to buy more .   That's great ! Thanks for your support . If any , please remember to call us . I am afraid I have to say goodbye now ! Bye , Mr . James !   Bye !
