In the afternoon, I contacted the installation technician, who was very professional

Extremely bad. After buying two long handles, the asymmetry is obvious. The distance between the two sides and the central axis is more than two centimeters. When moving, they can only grasp the small handle and negotiate with Shu Hua many times. The technicians simply and rudely ignore the length of the handle or the bending angle parameters, which is in line with the error range anyway. I have never accepted this so-called error range. Shu Hua told me to replace the parts, and then they were always out of stock. A month and a half has passed since I bought them on June 1, but there is still no solution. negative comment!
