I am a CUSTOMER and I have been using Dknir airsystems co for a while now. I must say, their products are of average quality. The performance is decent, but there is definitely room for improvement. The customer service is quick to respond to queries and resolve issues. However, I have encountered a few problems with their delivery service. Overall, I would rate them as average.
