What to know before buying

Listing details to confirm

The listing is inconsistent about identity and settings: its title and several descriptions identify EW-DJ4B-G511, but the model field names EW-DJ10 with 2 water-jet modes. One feature says five pressure settings while the title and other material describe four. The listed UK 2 pin plug power configuration also sits alongside rechargeable claims, and the charging stand and charge-time details are not consistently specified. Confirm the exact model, settings and charging arrangement for the selected listing.
