As long as there are no offline products, you can buy parts. When my things break, you contact the after-sales service staff to ask them to buy parts, so you don't have to bother yourself~
If you want to buy it online, you can definitely buy it. There is a universal treasure. But I suggest you contact the after-sales service to let the after-sales service buy you parts. The parts you buy yourself are not guaranteed. Besides, you need to find someone to reassure you. It's better to hand these things over to the after-sales maintenance master. You can also save your worry. The professional master can handle them properly. Isn't it wonderful!
