Oral-B Genius 8000 Review - UK 

Thanks for the comment. The battery should not degrade as you say that quickly. Yes they can fail in time. Some will degrade sooner than others, but the thing to know is that under the warranty period they are usually covered. Depending on the brush you go for, will depend on the warranty, but with most Oral-B models you get a 2 year warranty. Register online and you get a 3rd year free. What this means, is because the battery is built in, should it fail or get worse within this time, it should be repaired or replaced under the warranty, kind of getting round the issue, should it happen.

that's nice to know i should look into that the next time i get a brush,thanks for the reply

Try closing the app on the phone and restarting it. Power the brush handle off for a minute and then try repairing.

Yes it is. The Pro 2 2500 has up to 9,900 oscillations and 45,000 pulsations whereas the Genius 8000 has up to 10,500 oscilations and 48,000 pulsations.

@@ElectricTeeth can you fell a difference in the power

Yes and no. You would have to really use side by side to compare and you soon get used to each. If power is the only thing drawing you to the 8000 over the 2 2500, its not worth it.

The brush is water resistant, rather than waterproof. A rinse under the tap should be absolutely fine. Don't submerge the brush in water.

Electric Teeth Thank you so much. 😊

We have seen it in slow-mo. It goes back and forth in a circular motion. It does not complete a full 360 degree spin.

Good question and there is no exact answer. The warranty is for 2 years with an option to extend for another year to 3. However it could last a lot longer. We have brush that is 5 years old and still working!

Brian, Thanks for the comment. Indeed we do not mention that the brush uses a lithium battery, but we do talk about the battery life. Our view is that most are not too worried about the exact technology of the battery but more about the usage time. The use of lithium battery inside the brush does on a day to day basis does not make a significant difference to every day use for the brush user that we are aware of, perhaps you can advise, if we are missing something.

Hi Electric Teeth and thanks for responding! My thinking was against the backdrop of my experience with Braun electric brushes. Over the past 10 or so years our family has replaced Braun brushes on average every 2-3 years - due simply to embedded batteries prematurely dying. Nobody is perfect at recharging their device batteries the correct way (and there is definitely a correct AND incorrect way for different battery technologies) and so the batteries would die. Like smartphone makers making non-removable batteries now, Braun's batteries in these brushes are non-removable. Builtin obsolescence at its finest. This brings us to the discussion on battery tech. The traditional tech used by Braun was Nickel Metal Hydride (NiMh) and was only marginally better than Nickel Cadmium (NiCad) for the dreaded 'memory effect' with which I am sure we are all only too familiar. This memory effect WILL kill a battery inside 2-3 years (typically closer to 2yrs) due to the inattentive charging methods used. You can't simply recharge a NiMh battery at half charge all the time. You will virtually halve the life. Our kids paid no attention to charging rules and simply left the thing on the charger 24/7. regardless of what a manufacturer says, this will kill a battery well before time. Manufacturers will endorse (by omission) the slack battery charging habits as they want to sell more. The move to lithium (albeit well past due in Braun's case) is a move to keep up with the competition and gain market share only. If it was more altruistic and to benefit the consumer then they would go the full route and make it a non-removable lithium battery. This way when the battery dies (they all do eventually) the device would not have to be wastefully thrown away. FAR too much waste in our society plaguing the environment these days and manufacturers, like the phone makers, are mostly to blame. Enter the new LITHIUM battery. In the case of the wonderful Braun electric series this is singularly the best innovation they could have made. The phone linking nonsense leaves me cold . . . read . . . GIMMICK. Braun should have used lithium batteries at least 5 years ago. God knows why they persisted with such useless, not-fit-for-purpose NiMh batteries for so long. Lithium has virtually NO memory effect and can be charged by the least caring, inattentive member of the household whenever they feel like it (within reason). Lithium batteries have a MUCH better power-to-weight ratio and energy density. It is VERY interesting they have now included a 6 month money back guarrantee AND a 2 YEAR warranty. With lithium batteries this should be a 5 year guarantee. The design and mechanicals of the brush have never been a reason we have had to replace ours - just the batteries. The brush, I feel, would have no worries under a 5 year warranty term. Any argument that purports to say waterproofing is the reason for non-removable batteries is bunkum. There are a number of smartphones on the market which are waterproof AND have removable batteries. So yes, the review should have mentioned the (for Braun) revolutionary change to LITHIUM batteries. Most people know what lithium batteries are these days - they know they're the best - BUT most of them probably do not know that Braun only ever used NiMh to date. Believe me, I'm no dummy when it comes to searching websites and I cannot find a single reference to the type of batteries used in their pre-lithium brushes. It is only on the bottom of some brushes in microscopic writing and even then will only say "NiMh" - most won't look let alone know what that means. It is ONLY the change to lithium that will have me buying an 8000 and not defecting to Philips. I am sick of these NiMh dying batteries causing me to throw out otherwise perfectly good brushes!! So, after all that, my current NiMh-powered 7000 Braun brush died last week, again, UHHGG! I am off tomorrow to buy a special twin-pack of 8000 models with the lithium batteries for the first time. I'm looking forward to at least 4 years given enough care and I'm also looking forward to dumping the smartphone mirror-sticking holder in the bin as soon as I open the box. Honestly, who at Braun truly thought that would be a good idea?! :-) Having my beautiful Galaxy Note covered in toothbrush spray over the course of weeks/months is totally gross. After 50 years brushing my own teeth I think I know how much time to spend on each "quarter" by now. Sheeeeshhh! Toothbrushing for Dummies 101? The only 'possible' advantage of such folly 'could' be to get recalcitrant kids to brush their teeth. Maybe. Cheers, Brian.

Thanks for the VERY detailed reply Brian. i do agree with some of your points there, but even with the older battery technology, the warranty for most was good enough and lasted long enough that if the battery failed, Oral-B would likely have fixed or replaced it under warranty. I appreciate this is a hassle but the option was there. Few products come with a 5 year guarantee, and with Oral-B you can increase this to 3 by registering the brush online once you get it. Let's hope the 8000 lives up to all your expectations. I would be truly grateful to hear your comments after a few weeks of use.

That's interesting about the 3 year warranty for registering online. I hope that's in Australia, I imagine you're in England(?). It is a good innovation to see. I have just right now ordered the 8000 twinset online so here in 2-5 days. Will report back. I've no doubts whatsoever it will clean my teeth exceptionally well - all the Braun/Oral B brushes have. The charging story will be the interest focus for me; how long it takes to charge, how long a charge lasts when being used, how long a charge lasts when NOT being used are the things I will possess over! I will play once with the bluetooth nonsense before I bin it as I am paying for the silly thing after all! Let you know how that goes too! Thanks for your interest and time. Chat soon. Cheers, Brian (Sydney, Australia)

Ahh yes Brian, we are in England....Check your paperwork when you get it to see if there is any reference to an extended warranty. Look forward to hearing your thoughts.
