Is it necessary to do the crystal coating offered by the 4S shop, with a labor cost of 399?

Understood. If you have any content that needs translation, feel free to share it.

Deceptive

Keep it for car washing.

The free screen protector is really bad. The original one costs an extra 1680... Such a rip-off.

No labor charge, just like my free coating.

Not necessary [grin]

Oh, do they charge labor fees for the free items?
