What owners single out
In their words
“The IO5 has had, in my experience, great performance and offered a very thorough clean. The different functions are fantastic, and have come in handy when I recently experienced some gum sensitivity after dental works, the sensitivity and sensitive plus settings were perfect to avoid pain and soreness while still getting a proper clean.”

“I have been unhappy with my electric toothbrush purchases changing every 6 months when they made my gums bleed, gross furry teeth feeling, difficult buttons to use etc. The iO5 has been a breath of minty fresh air! It is lightweight & sleek in design. It is easy to use and navigate/understand the different modes. For me (F 47) the 360 pressure sensor is fantastic.”
