What to know before buying

Listing details to confirm

Customer feedback reports mixed instruction quality, reports of missing parts and inconsistent experiences with motor function. Battery information conflicts: product details specify 6 AA batteries, while a feature description says 6 AAA batteries. The claimed four-speed and lever-operated mechanism also sits alongside a listed manual operation mode, and the listing does not clearly establish how those descriptions relate. Check the selected listing's battery and operation details before purchase.
