Hi, I'm Jenny, I'm Jack's partner and although I don't like him very much (because the prices he gives me don't always make me more money, hahaha) I'm still willing to write him a customer feedback. As an international buyer I have to deal with a lot of things every day. In particular, my inbox is constantly full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Jack's emails always give me a better understanding of the product and the industry.
Also I am very happy with his service. He has been the easiest supplier for me to work with and has facilitated all the details of my work, saving me more energy to deal with other things. Although his prices are not the lowest among all suppliers, his products give me the most peace of mind. ---- Jenny, Purchasing Manager from a certain company
