Verdict
electronegative ions ? Toothpaste - less brush ? It might sound like something out of the back pages of a funny book , but the ION - Sei ’s alone plaque - removing , bacteria - repelling tech seems to do the whoremonger . You ’re paying for the tech though , as other fancy feature like multiple fashion , Bluetooth connectivity , and imperativeness sensitiveness are all absent .

Key Features
Introduction
The Sanyei ION - Sei is a transonic toothbrush that place upright head and shoulders above the cooky - cutter competition , thanks to its innovative use of negative ions .
It blasts your teeth with damaging ions which not only help destabilise and untie plaque , but also prevent enamel - eat away bacterium from sequester in the first position . Oh , and it does n’t even require toothpaste to make its magic .
However , with a relatively unknown presence and a cost ticket of £ 129.99/$149.99 , it fall just shy of impulse buy - to - try territory . So , is it worth it ? Here are my persuasion .
Design and accessories
Available in a range of mountains of attractive color – admit a delightful pastel Sakura Pink , Lake , Moon Grey , and Day White – this is a soup-strainer that ’s dressed to move .
And while pattern is very much subjective , I ’m rather drawn to its tops - glossy shaping body , with its overly prominent curved shape and futuristic Matrix - esque baptistry .
Round the back , you ’ll find something unique – a long , wood coal - greyness strip that feels like a mix between credit card and graphite .
This is the electric conductivity handgrip , which works in turn with a especially - contrive question to help produce those all - significant ion you ’ve heard so much about .
Overall , it makes a confident , visually appealing statement , albeit one that ’s a far war cry away from the subtle designs offer by soup-strainer in the Sonicare or Oral - Bel range . But that ’s fine by me . It ’s a welcome breathing spell of fresh air , specially when sit securely in the equally - glossy Micro - USB charging dock ( which , while notUSB - C , is still better than anything that requires a specific socket ) .
With two brushwood head include ( one hard , one soft ) and a solid , durable - feeling build , you wo n’t experience suddenly - transfer , although I do have one major niggle . While there is a build - in two - minute timekeeper , the ION - Sei lacks any form of press sensitivity reading , so you wo n’t know if you ’re brushing too hard .
Performance
There are two chief components in the ION - Sei that work together to let it perform its magic . The first of these works by using a small replaceable battery that ’s construct into the handle of the toothbrush ( and can be replaced easily by transfer a small fuck ) . This battery is get in touch to a titanium dioxide bar that draw throughout the distance of the toothbrush , before being exposed at the neck . It ’s this exposed section that the toothbrush head slots over .
Before you brush your teeth , you wash this bar by running water over the brush head . When your fingers transfix the rear conductor panel , the wetness creates a closed body circuit that menstruate from the toothbrush to your mouth . When you sweep , a washy stream is generated , and negative ions flood into your oral cavity and across your tooth .
The second spell of this rather cagy solvent bring us once again to the Ti oxide Browning automatic rifle that lie within the copse drumhead . A construct - in UV LED light bathe the bar , producing more negative ions , which are then convey into your lip by water and spit . But what makes these negative ions so special ?
Quite a few thing , it flex out . For starters , negative ions are extremely mentally ill , so they ’re desperate to stick to other particle to stabilise themselves . In this example , they have memorial tablet hard set in their site , attracting them and weakening their adherence to your teeth , make for loose plaque remotion when brushing .
In addition , your tooth will be coated with these negative ion during the brushing process , which will naturally repel negatively shoot streptococcus mutans and porphyromonas gingivalis bacterium . The former feeds on sugar to erode tooth enamel , while the latter eats away at gums , cause awful recession and tooth loss . It ’s all very clever poppycock , andclinically provento boot .
Does all of this fancy disconfirming ion technical school work ? In my case , yes . During my six - week examination stop , I could visibly see a decrease in brass . While I was also reviewing a few other electric toothbrush at the same time , there was an intersection period where the ION - Sei was my day-by-day machine driver , and I can confidently say that my overall dental hygienics feel good .
Even without toothpaste , the post - brush sensation felt refreshingly sporting and almost tingly , with a pleasant sense impression of polished teeth . Whether this is all due to the ions or the transonic head , I ca n’t say , but it ’s a sensation that I continue to bask to this day .
While I initially ditched toothpaste and brushed purely with water as advertised , it feel wrong to bequeath the bathroom without any minty freshness . This brushing can be used with toothpaste , if only for the feeling it leaves .
We also put my trustworthy plate through various tests , including beet and spinach . The soft nature of the ION - Sei think that it removed less physical junk than some rivals , but this will be a incentive to those that detest overly - brawny electric soup-strainer that may cause discomfort or sensitivity . The three intensity levels can be choose by pressing the magnate button during use , and even the most brawny one felt pleasantly blue-blooded .
The bristle on the included brush top dog are also some of the good I ’ve ever used . They ’re incredibly prospicient , and ok , provide excellent levels of flexibleness while stay on firm enough to put in some proper body of work . They also seem to be much more undestroyable than any others I ’ve test , and I view they ’ll last considerably longer than many other alternative .
shelling life is officially stated to be around two to three weeks , which is quite a generous range . In my case , I ’d say it survive about two weeks or just under . It takes quite a long clock time to charge this brush , so it ’s best pinch up overnight .

Final Thoughts
Despite it being an strange option , I think many people would delight the blue-blooded - yet - tingly brush experience served up by the ION - Sei . Its scientifically / anecdotally - back negatively charged ion technical school really does appear to reduce plaque and improve dental health , and its brushwood heads are some of the good I ’ve used .
