Portable oral irrigator with 5 modes and IPX7 waterproof function. - Model Name: FS-101 - Waterproof Rating: IPX7 - Water Capacity: 160ml - Number of Modes: 5 modes - Battery Capacity: 1200mAh Included: USB cable (dedicated charging cable) : 1 nozzle (unused) : Instruction manual I used it once after purchase, but the water pressure was stronger than I expected, so I stopped using it. There were two nozzles included, so I will include one unused one. (The two nozzles were packaged together in one bag, so the bag is slightly open where I took one out, please understand.) Thank you for looking.
