Is 50,000 VPM better than a normal electric toothbrush?

Most sonic brushes run around 30,000 to 40,000 vibrations per minute, so this is on the high end. Higher vibration counts do not automatically clean better; brush head design and your technique matter more.

How long does the battery really last?

The stated figure is up to 180 days per charge, which assumes short twice-daily sessions. Expect less if you use higher modes or brush longer.

Does it come with replacement heads?

Yes. The box includes four DuPont soft-bristle W-design heads, stated to cover about a year of use.

Can I use it in the shower?

Yes. It is rated IPX7, meaning it can be submerged briefly and is safe in the bath or shower.

Does it have a pressure sensor?

No pressure sensor is listed. Watch for pressing too hard, especially on the higher modes.

When is the best time to buy it?
