I engaged Asia Top Investigation to conduct surveillance and investigation on my spouse. I had suspicions that he was having an affair. I chose this agency because of their excellent articles about them in the press. I am so glad I did so. I got what I needed. Vincent and his team were exceptional. I was given prompt updates. The photos and videos provided to me were comprehensive. All were compiled and reported diligently as soon as the job was completed. Vincent not only acted as my PI but also provided me good advice ensuring that I do not make any rash decisions regarding my marriage. He will call and give updates and at the same time ensure that I remain compose and calm receiving the evidences. After job completion, a follow-up was also done to ensure all were good. Vincent goes beyond miles to help his client. Indeed an experienced investigator. I would not hesitate to recommend this agency to those that really need it. Thank You!

Vincent, I will highly recommend anyone who needs your services. I have been through lots of stress trying to engage a reliable private investigator. The journey of getting one is not easy. I was fortunate that I engaged you. Your surveillance team was professional. When things don't get into place, I was amazed by the way you guide your team even in the middle of the night. I'm happy with your report. Thank you👍

Vincent, the thing I appreciate most about your agency is that you are very fast to respond to my enquiries and your live updates are super, responsible in what you have promised and transparent on your charges. Most importantly your experience in handling my case on how to get the evidence legally and troubleshoot when the operation did not go according to our plans. My lawyer commented that your report is well written. Thank you.
