For a beginner with an electric toothbrush, the AI assistant is really cool - it shows you where to brush, for how long, but sometimes it gets lost.
Compared to a classic toothbrush, better cleaning feeling
Richly equipped brush
AI assistant
At least some accessories
AI assistant is a cool thing, but it doesn't have much accuracy, sometimes it's infuriating when it doesn't want to take the last section of teeth
The rechargeable travel case is only one and looks very cheap
The magnetic charger has its own specific connector - it could also be USB-C
Only 2 heads in the pack - for that price they could have given at least 3 - one of each available head.

I bought it as a Christmas present and I could not get my teeth so well cleaned with a normal toothbrush. After the first use I had to get used to the vibrations but thanks to the ultra sensitive mode it is easy to get used to. As for the 3D mapping, it's a slight struggle to get it to read your teeth correctly (I brush the right upper palate of my teeth and it shows the left side on the map), but otherwise a great investment and I recommend it to anyone deciding on an electric toothbrush.

I was buying on sale with cashback for 6400kč for 2 pcs. That seems fair to me. Overall, the toothbrush is nicely crafted. It recharges in about 3 hours, which is fine. The vibration intensity is significantly higher than the previous low-cost model. The endurance is overestimated, it lasts me about 7 days. I'm satisfied.

I am satisfied with the brush - I have the second one, the previous one lasted 4 years (probably the battery died). The result of brushing my teeth seems to me more perfect than with an ordinary toothbrush. The dentist no longer points out to me, as she used to, the places I should focus more on. The dental hygienist also complimented me on my choice of this toothbrush. The previous toothbrush (same type - generation 6) lasted me 4 years, then the battery died (I think).
more perfectly cleaned teeth
when using the app, you can clearly see which part of the teeth, for how long and how well you cleaned
also recommended by a dental hygienist
mode selection as required
sometimes it doesn't seem to recognize well where I'm cleaning

A great investment when used properly to preserve your own teeth (but don't forget about the spaces between the teeth - interdental brushes, at the very least, to make them tighter + interdental "shower"). All in all, an effective prevention of sci-fi denture bills, assuming of course that it's not too late.
In addition, there is usually a lower dental hygiene fee for the dentist (to be done at least once a year, because some tartar "climbs" around the cervixes to the roots anyway).
