I bought the cheapest one that had a pressure sensor. It was a Philips Sonicare 3100 series. It was 55$ CAD. The heads are pretty expensive but I buy bamboo ones instead

Hi! I have pretty fucked up teeth so I've had a lot of recommendations from dentists etc over the years. Oral-B and Philips Sonicare are the two market leaders and the ones I would go for. They have been around a long time and will most likely continue to be around, meaning availability of spare brush heads, replacement chargers etc is most likely to continue throughout the life of the toothbrush. The main difference between the two is the brush type. Sonicare has the ultrasonic agitation, but a longer, more oval shaped brush head. Oral-B lacks the ultrasonic, (though they do have a similar 'pulsonic' range), but has rotating brush heads that are round. I have had both and personally I prefer Oral-B as I find them easier to get good contact along the tooth surface, especially in molars, and easier to get in behind the molars etc too. You may have a different preference and if you've been using manual brushes so far, Sonicare will have a more familiar shape. Avoid the higher end ones from each brand, they are adding in connected services and all sorts of extra gubbins that just means more electronics and therefore more potential points of failure, ergo reduced BIFL-ness. The only additional feature other than being a toothbrush that I would recommend would be an indicator of brushing pressure (my Oral-B has a red light on the back) - users switching from manual brushes often brush too hard and over time this can cause damage. Something like the Oral-B Pro 3 3000 would fit the bill. Everything you need and nothing you don't. Philips equivalent would be something like the Sonicare 3100 series.

Nekem és a feleségemnek Philips Sonicare 3100 van, a gyerekeknek Philips Sonicare for Kids típust vettem. (Egyszere cseréltem négyünknek, a plusz fejekkel így is 100 ropi körül volt)

Yes, I've had a Philips one toothbrush and a sonicare 3100 (or similar, can't remember the model, but it was one of the cheapest models), and it's pretty much the same.

Entry Sonicare, but with the pressure sensor. Our first lasted over 20 years. We're 3 years into the new versions. I think they're 3100 or 4100

I would recommend spending a few more dollars to at least upgrade to the 3100 for the pressure sensor. There is a tendency to press too hard with these electric brushes and you can really wear away your gums. The senor gives you an audible and tactile warning so you don't do that
