Oral-BiO9 Electric Toothbrushes For Adults, App Connected Handle, 1 Toothbrush Head, Charging Travel Case & Magnetic Pouch, 7 Modes, 2 Pin Plug, Special Edition

I've been a longtime Sonicare DiamondClean user, having purchased two of them (after the first one broke); I bought my first one in 2011 for £250 when they first came out and then its replacement for £97 in 2016 (having just checked my Amazon purchases!), and lots of replacement brush heads since then.The DiamondClean is an excellent toothbrush, and I'm not adverse to spending good money on occasion with devices that help keep your teeth in good condition.. it's a lot cheaper than dental work!I noticed about a year ago that I was getting coffee staines on the bottom of my eyeteeth and despite my best efforts with a new toothbrush head for my Sonicare, I couldn't get rid of them and had to get a charcoal-based stain remover stick that fortunately worked. But I realised at this point that I was skipping my routine with the Sonicare. My preference has always been scrubbing my teeth like a traditional toothbrush which is what you do with Sonicare.. it's like manual brushing on steroids. But it was clear that I wasn't concentrating on brushing.One thing I didn't like about the Sonicare was they stopped making the smaller brush heads that I preferred. You can now buy knockoff versions but they're just not as good, so I was forced to buy the standard/bigger brush heads, which never felt as good for me.So about a year ago I had a look for Oral-B and thought it wouldn't hurt to get one of the cheaper models to see if it would help with the staining and of course they have smaller brush heads... I couldn't believe how sore my gums were, particularly around the top corners after the first use with the Oral-B, which was a clear indication that I wasn't cleaning effectively with the Sonicare, so I started to alternate between the Sonicare and cheap Oral-B.Fast forward a year and I saw the iO 9 was on one of its frequent half-price offers (why Oral-B does this in Europe is beyond me as their US prices are kept much lower without the near constant offers) and I decided to go ahead and see if the Sonicare-like vibrations would make much of a difference....I've used it twice and I know it's a cliche but it really does feel like I just left the dentist..And once again I have sore points where its clearly hitting points neither of my Sonicare or cheap Oral-B go to. One interesting thing I've noticed is that I don't need to rinse my mouth out with water. It seems to be so effective in using up the toothpaste, there's no residue to rinse out. I just use mouthwash after a minute instead.I haven't tried the app with bluetooth yet but I'm blown away just how effective this toothbrush is. The heads also seems to be a little cheaper than Sonicare, too.One word of warning though.. you'd be insane to pay the circa £500 full retail price this device, hence why they're often on 50% or more sales prices. You should also check the comparison matrix to see what features you need as the iO6, 7, 8, 9 & 10 all offer the same basic 'micro-vibration' cleaning and I don't see the 9 or 10 being any better in its core cleaning function in this regard. The day after I purchased this, it went back to full price and the lower models went on discount. Had I of known that, I might have gone with a cheaper model, but overall I'm very happy with it.One slight disappointment is the travel case.. this uses its own proprietary lead whereas the Sonicare has a USB-based travel charging case, so you need to take a separate cable along with the case for the Oral-B unfortunately. It looks like they've improved the iO 10 with a battery-based travel case but it currently sells for a crazy £800 price upon checking at the time of writing, and the brush functions appear to be the same as the iO 9.

Great toothbrush, travel case is really handy and allows for charging on the go. Battery life is good and easy to use.

Best toothbrush that I had so far but the price is far beyond limits. Don’t know was the difference between IO9 and IO10. I paid 250£ on mine in December.At least at this price you expecting a spare head for this but hey nothing extra. Oral B. You decide if you want to paid the price.

Unfortunately mine arrived incorrectly so I had to send it back, none the less when the correct product arrived it was great. Good battery life, I love the functionality where it says time spent brushing and the different settings. Also a very good size that comes with a travel case.Highly recommend

Yes, a brilliant brush and a real heavyweight. I found the charging system a bit confusing so make sure that the charger is the correct way up. It needs to have the slight dome fitting into the recess in the base of the brush. Brilliant brush. My dentist will love it. Even tells you what it is going to do, so that you can change it seems to run on imojis and not happy if you do not spend long enough cleaning on daily clean setting. Will give a soft clean and even clean your tongue. A real find.

Really good quality clean. Feels much less clean when I use another toothbrush.Battery has been faulty after 18 months twice. Long term reliability issues.

I bought this toothbrush after a recommendation by my dentist but they also had a discount offer on them so perhaps that was related. Ended up buying on Amazon Prime Day and went for the io9 because I wanted the charging case. Having used this for a couple of months now I actually wish I had not bought it. It has leaked toothpaste and saliva on every use. It drips down from the brush-head all down the main unit and your hand and will end up down your arm unless you hold it carefully. It’s so badly designed I’ve tried contacting the manufacturer as I believe this has been mis-sold with false advertising. A quick online search will tell you everyone has the same issue with it. Oral B support have said there is nothing that can be fixed/replaced under warranty and had the audacity to state that the design has been based on customer testing. No-one in their right mind would want to battle this mess twice a day, especially after paying for a luxury good at a premium price. Such a disappointing waste of money. Would give no stars if I could..

I didn’t think a toothbrush could feel luxurious—but here we are. The Oral-B iO9 is seriously impressive. The brushing experience is smooth, powerful, and feels like a full-on dentist clean every time.The pressure sensor is a lifesaver (no more aggressive scrubbing), and the app makes it kind of fun to keep track of your brushing habits. The real-time feedback sounds gimmicky but actually helps improve technique.Battery life is great, the charging stand looks sleek, and the travel case is a nice bonus. Is it expensive? Yes. Is it worth it? If you care about your teeth and love gadgets—absolutely.
