Note: Swiss 7075 T6 is an extremely rigid aluminum material. In some rare cases some small cracks may occur (for example, around openings or on edges where tension in the material is highest). Those small cracks are a natural effect and have no negative impact on the performance, reliability, or lifespan of the product, and as such are not considered to be a defect.
Due the nature of the aluminum material and the machining process, it is normal that the chassis may be slightly bent in the longitudinal direction.
