The service is disgusting! I ordered safety glasses with carbon lenses. After 3 months, one lens mount fell off. I applied here for repairs, and they threw up their hands. They said they wouldn't fix it. This is not a warranty case. The screw is broken. The time limit for detecting a factory defect is 30 days. And then the guarantee is not provided at all. I would not recommend this optics. They sell substandard goods and the work is substandard, respectively. The price for the glasses is 230p, with work and enough for 3 months. At the same time, I used the glasses for their intended purpose and kept them in a case, since these lenses are very fragile. Even with such careful use, the screw couldn't stand it. And I have enough conscience to suggest putting expensive lenses in Chinese bullshit.
