I don't know about the pros, but for me there are only cons.... The job was to photograph the details, an ordinary plane, even half a meter in size would not be, without any tolerances,,,, agreed on one amount over the phone, all photos were sent before the trip... As a result, upon arrival, the amount was increased by 180 percent, since it is very difficult to attach these details, but it was not visible from the photo!?so the work was carried out for more than 12 days.... I definitely do not recommend it... Be careful and if you choose such a service, then stand your ground.... This organization does not issue any documents or checks!!!!
I wanted to fix the engine, but I looked at their conditions and changed my mind, I don't want to say anything, maybe the specialists are cool, but the first impressions are so-so.
