The quality control that I have experienced from this company has been very good so far. They are always willing to work with you no matter what your needs or requirements may be! Sometimes it can take some time for them to get back to me but they do listen when we talk about our business problems/needs/wants etc. We've used their team before at another client where there was an issue regarding one part being faulty. This happened twice over two years ago now. That same year both times i had my car serviced by these guys who were also working under Worldlogs. Both cars broke down within days after getting fixed. So please don't go anywhere else if possible because as long as you're dealing with WORLDLOGS, everything will run smoothly. It does cost more than other companies out here however sometimes even though something isn't.
