No matter which brand of your components, all of them have good one and defective one.
For example, we use RECI, EFR, EF, Yongli laser tube etc before, but why we choose SPT finally?
Actually, their technology is almost the same, however, we have high requirements for the tube,
we will return it back if the tubes can't pass our 1 month testing.
But how do they process these defective laser tubes? I really don't know, maybe sell to other manufacturers at lower price.
This is why the same brand components have different quality.
And yes, most manufacturers don't have QC department, you don't know what's wrong with the components before you assemble the laser machine.
Usually, they don't test the laser finally, or just a short time test and pick it directly. You really don't know what problem you will have when you get the laser.
Cheap components, no testing, no QC department, low labor fee, no after sales services, they can save much money on it.
