When I met RONSCO at the Dutch stainless steel show in 2015, I just left the contacts. Although Cady has been taking pains to follow up our cooperation, our company has a strict supplier audit process, and we have no cooperation from 2013 to 18 years. During this period, we will still attend every Dutch stainless steel exhibition, and RONSCO is always an exhibitor. Every time, he would send us a polite email to ask us to visit their booth.

Until the 19th year, the supplier we cooperated with had problems. We were told that the goods we used to build the power plant could not be delivered. If the goods could not be delivered on time, we would lose nearly 200,000 dollars. We had to try to talk to Cady, and finally started our first cooperation with RONSCO. Although we tried to place large orders in the first cooperation, we had no choice. Finally, to our surprise, RONSCO is not only more advantageous in price, but also very skilled in quality control. For the temporarily added orders, we need the cooperation of the supplier. Here, I really appreciate Cady's timely follow-up.

When I was working with RONSCO, I was just starting my import business. My friend told me to look for suppliers in alibaba, but everything seems not so simple. I found a supplier on alibaba at first, the price was very attractive, and finally I received a pile of garbage. After working with RONSCO, Neo gave me lots of useful advice, I appreciate most is the company to the customer patience, remember once, because of my problems lead to problems of the bill of lading, I shut up, tens of thousands of dollars worth of goods buckle at the customs, the losses for I really can't afford the newly established company, at that time I am very anxious, unceasingly in the Neo without handle, also complained that it won't work with RONSCO again.

Neo is very tolerant of my bad temper, never accused me, and then constantly contact the forwarder, the best time in the customs to help me pick up the goods. I felt ashamed and apologized to him. RONSCO always emphasizes that problems should be dealt with as soon as they appear, and then who is right and who is wrong after the problems are solved. Now we have cooperated for two years, and my company is also developing well now. I would like to thank RONSCO as the supplier here.

What I admire most about RONSCO is their attention to detail. Each of them seems to strive for perfection. I have visited RONSCO's factory many times. They are very busy and their business is very good. Every time I go to China, I like to visit their factory. What I value most is quality. Both my own products and the products they produce for other customers need good quality, so as to reflect the strength of this factory. So every time I have to go to their production line to see the quality of the products they produce, I am very happy, over the years, their quality is still so good, and for different markets, their control of quality also follows the market changes.

Communication is the biggest problem in international trade. Every time I was very careful to make sure that all the details were in place. In the past 4 years of cooperation with RONSCO, the only major accident we had was due to a communication problem, which resulted in the inconsistent logo of our products. The atmosphere was tense, we were all angry and none of us wanted this to happen. In the end, it was RONSCO who took the responsibility, and we agreed with half a half to take the responsibility this time.

Although we will have disputes, RONSCO is able to control his emotions and take the responsibility to pay compensation, which makes me trust their character very much. Later, we have strengthened communication and become more proficient in cooperation. We are now strategic partners.
