lost 46 days and 610 euros with them.
I am very dissatisfied with the quality of their work. After the measurements, they promised to report the results in 14 days, it turned out that in favor of large orders, they decided to postpone the execution of my order, as a result, I waited 46 days.
After which it turned out that they measured the wrong thing, since they did not initially find out what exactly needed to be measured, but followed my instructions knowing that I do not understand this issue.
I feel vibration with the internal organs of the body, which probably comes from the port. They made within 24 hours vibration measurements, and did not find a defect.
After the examination, it turned out that before the vibration examination began, they were inclined to believe that the matter was in infrasound, although they did not tell me about this.
I lost 610 euros and time.
