Does a product broken must be due to the poor quality? 대한민국

The answer is NO. There are many external factors that can cause product failures, such as:

When the vehicle is submerged in water, it can cause the motor to malfunction, the air pump to supply insufficient air, and the fuse to burn out.

In addition, when dust or small debris accidentally enters the interior of the distribution valve, it can affect the operation and normal use of the distribution valve. 

So when you encounter problems related to malfunctions, please promptly investigate the specific causes and adopt the correct solutions. If there are any product quality issues, please contact us in a timely manner.
