I got the OralB io6 for a good price on the German Amazon, they seem to have pretty good offers there

TL;DR: Go electric, it's worth it 👌 My last three dentists have all recommended electric toothbrushes without hesitation, saying they're clearly superior to manual ones. I wish I'd made the switch sooner. I went with the Oral-B iO Series 6. While I'm happy with it, I don't think the premium price of the latest models is justified, especially for a product that isn't BIFL. **Things to know before buying:** The toothbrush requires regular maintenance. The connection point where the brush head attaches accumulates grime in the small crevices, so you'll need to clean it frequently. I've also noticed dark stains (likely mold) developing on the rubber seal that I haven't been able to remove. Battery life degrades significantly over time. After two years, mine needs charging weekly instead of lasting several weeks. My wife's unit also developed charging issues after a single drop, sometimes it simply won't charge at all. The app is forgettable. I've never used it. I like it's not noisy. My brother has a cheaper one that is noisy as hell. **Bottom line:** Despite these drawbacks, I still think an electric toothbrush is a worthwhile investment. However, next time I'll research more thoroughly and consider spending extra for a model with better build quality and longevity.

I have the series 6. Did not need the features of the 9 and the 6 is pretty good. The new brushes are a real improvement and my teeth actually feel clean. Hope this helps

I doubt any will be good for life but the oral B line is great. I’ve been using the io5 or 6 for 4 years now. Just new heads every so often and clean it regularly.

Oral b iO6 is what I have. My dentist said that’s what she used (I think her version was a newer model, but iO6 is where my budget ended). The difference it makes in how clean your teeth feel is amazing. Night and day stuff from a manual brush. And it lights up red if you brush too hard which is super helpful to teach the correct amount of pressure… which is actually pretty light/ gentle. Definitely recommend it, I hate the pain of cavities and like having well kept teeth so it’s super worth it to me.

I have an oral-b io6. I miss my Sonicare. Dentist in the family swears by the Oral-B as the superior brush but I dunno. The brush heads in these wear out so, so, so fast.
