There will be a discount if you try it on. The main differences are: First, the price difference. One of the advantages of the prototype is its low price. According to the discounts of different shops, some prototypes can even be sold at a 50% discount. Authentic products are sold at the normal market price without discount.
Poor quality: the prototype has been placed for a long time, the appearance is worn, and the accessories are uneven. Authentic goods are picked up in the warehouse. Finally, there are some problems in the maintenance process of the prototype, such as the after-sales of the prototype has been changed from the default three-pack to one-pack, and the industry standard is still not perfect.
