I have been a customer of Dong il engineering & consultants co., ltd for several years now, and I must say that their services are average. I have had some issues with their communication and response time, which is why I cannot rate them higher. However, overall, they do get the job done and their prices are reasonable. I hope they can improve in certain areas to provide a better experience for their customers.
