Detailed Answer
Accessory purchasing: 1. Original manufacturer website/flagship store (most reliable); 2. Authorized dealers (bulk discounts); 3. Service outlets (on-site replacement). Notes: verify the model, ask for an invoice, confirm the warranty. Lider/Xingjia provide accessory supply and inquiry services. Buy consumables together with the unit (as spares).
