Bought with my own money - Braun Oral-B CrossAction Power Whitening Electric Toothbrush

This is an affordable electric toothbrush. I think I paid around 20,000 to 30,000 won at the supermarket, including the replacement brush heads.

I used to use an electric toothbrush in the 200,000 won range a long time ago.

I used bamboo and biodegradable toothbrushes for a while, but now I am back to an entry-level electric toothbrush.

I switched to Oral-B CrossAction Power Whitening.

The bristles do not have only a round part like typical electric toothbrush bristles.

There is also a fixed part at the bottom, so you can brush your teeth as much as you want.

I keep buying refill toothbrush heads at Homeplus.

Replacing the brush head is easy, and it uses one battery.
