Customer Review Highlights:

“These guys are quite great! We could have expected nothing more! We selected them to help us out by going through the google reviews. We have never met them in person or never knew where they were. Yet through telephone conversations and emails alone we got the things done quite professionally and tactfully. In the middle of the process our situation changed and some of the agreed work had to be cancelled. At this point they showed a great level of understanding and promptly returned a $1000 deposit we had kept with them. Our experience with them was quite satisfying and helpful. Without any hesitation I can recommend Spousebusters for anyone who wants their services.”

“I live in Canada and needed surveillance of my wife on very short notice as she booked a sudden trip to Sydney leaving me very suspicious of what she would be doing there and with who. She had been exhibiting some very disturbing and bewildering behavior over the past year or so. Josh and a co-investigator performed some extremely difficult tracking through many busy locations and provided timely updates as the surveillance progressed late into the evening. Video, photos, and a report were supplied. Much to my relief nothing was found that indicated any type of infidelity and eased my mind in this difficult time. The service from Elite Surveillance was outstanding. Very quick, courteous, and efficient. Would definitely recommend to anyone looking for a top notch investigation firm.”
