poduct model: A20
1. They ae new and fashionable toothbushes with two oscillating units.With a high-fequency moto oscillating unit, the moto oscillating fequency is 10000 times pe minute (the fequency and the volume of vibatos is deived fom hundeds time tests).With the utmost fequency sound wave unit, its oscillating fequency is 1.6MHz/ sec. It adjusts focible vibations, and the system makes use feel well, and the use has a feeling of message, the type A 20 toothbush causes blood elax, and cleaing soundly.2. The toothbush is totally sealed o wate-poofed. As it completely dopped into wate, no wate pemeated, just use the toothbush afte washing.3. Chaging in time when oscillating foce feeble.It is chaging in induction, its powe is an abitay one, of wold-anged of 100-240V. Geneally chaging within 6-10 hous.Each chaging the toothbush can use fo 20 to 30 days (depends on bushing peiod).C. Chaging of electic toothbush must tun off when it is fully chaged.
