What to know before buying

Listing details to confirm

Listing details conflict: the title claims 129 accessories and the feature text lists a carrying case, small accessory case, Type-C power cord and manual, while the explicit included-components field names only the rotary tool. The stated 3.7V rechargeable tool also conflicts with a separate battery entry requiring a 9V battery. The listed 200-minute battery life has no operating conditions, so confirm the selected listing and runtime expectations before purchase.
