Review on Electric toothbrush Oral-B Smart 4 4900, black/pink by Alvin Hltan ᠌

A fantastic pair of brushes at the price of four thousand. When you don't use too much pressure on your teeth, you get a better clean. Replaceable nozzles from the manufacturer cost € 1,000 for two, but you can get them on AliExpress for a significant discount. Analogues have not yet been tested. I was able to purchase it for 3,700 after applying several discounts. The allowance is sufficient for a week and a half with daily cleaning costing 1 pound each day for two to three minutes. When there is a lot of pressure being applied, the red indicator lights up and vibrates in a different way. I installed an application that was provided by the manufacturer. It allows you to monitor the number of cleanings by date, switch modes on the brush, or turn them off entirely (normal cleaning, gentle cleaning, and whitening). However, the application is not very useful. despite its advantages. The time required to fully charge the device is greater than 12 hours. During this time, a green flash will appear on the indicator; after the battery is fully charged, the flashing will stop.
