I have been a customer of Guangzhou quanju ozone technology co., ltd for several years now, and I must say I am extremely satisfied with their products and services. The ozone generators I purchased from them have been working flawlessly and have helped improve the air quality in my home. Their customer support team is also very responsive and helpful. Overall, I would rate the company as excellent.
