What to know before buying

Listing details to confirm

The listing is inconsistent about included accessories: feature text claims two batteries, charger, 1000ml and 1500ml cups, filters, brush, needle, funnel, gloves and manual, while the detailed package list specifies a 1000ml pitcher, two batteries, gloves, cleaning needle, funnel, 10 filter papers, brush and five nozzles. It does not confirm a charger or the second cup in that detailed list. Check the selected listing for the exact kit. The listed 650 ml/min flow and 650W motor are manufacturer claims, not independently verified.
