As a writer, I feel obligated to discuss my terrible online purchasing experience with OUKANING. Their website was attractive, and they promised high-quality appliances and accessories for the home, but I was disappointed by what I received. I went to OUKANING's website in search of a new air purifier and discovered one that seemed ideal. After placing my order, I excitedly awaited its arrival. When it eventually arrive, however, I was dismayed to find that the product was not at all what had been advertised. The air cleaner looked and felt like it had been constructed on the cheap. It was of lower quality than promised on their website. The air cleaning performance was subpar at best, and the unit was rather loud during operation. I was quite disappointed to receive an unprofessional and condescending response from OUKANING's customer support when I tried to voice my dissatisfaction with the company. It was evident that they had no intention of addressing my issues or making things right. In general, I was not satisfied with my purchases from OUKANING. If you're thinking about making a purchase from them, I'd advise you to exercise caution and do some research on the products beforehand.
