Awesome!

Bought mine on Prime Day. This is a game changer. My most recent dental checkup, the hygienist said she hardly sees anyone that needed zero scraping, what are you doing..... well this thing is a game changer. I tossed all my other brushes.

Dreadful—head and wand are way too big

My husband and I bought these to replace those of a different brand. I do not like this toothbrush at all. It’s impossible for me to close my lips over the giant head, so spit runs out of my mouth and down my arm.

Excellent toothbrush.

My spouse gave me this OralB io5 for Christmas. This is the best electric toothbrush i have used. Althugh I have used the tootbrush for a short time, I can tell the difference after each brushing.

JUNK

Piece of garbage it started rusting 3 weeks in and then I take it with me on vacation and I go to use it and the bottom of it is cracked. Now I have a useless piece of garbage.

Extremely dissapppointed!

I have never had an electric toothbrush that rusts metal like this one. It's crack breaking after only 2 months. The quality doesn't justify the high price. It was a gift to my little kids. I need a refund.

We're truly sorry to hear this, Dayan. For your peace of mind, we check the quality of our toothbrushes many times during the manufacturing process so that you receive a good quality brush that will last, although rust can still develop if excessive water is left on it. Rest assured, the rust is not harmful and can be easily cleaned off using a sponge with water. To prevent rust from developing, we advise removing the brush head from the handle after each use and cleaning them separately under running water. Please ensure both parts are dried thoroughly before reassembling to help keep your brush in its best condition. If you need further help, we're happy to assist M-F, 9 AM to 6 PM EST at 1-800-566-7252.

So fresh and So clean!

[This review was collected as part of a promotion.] I am in love! My teeth feel so squeaky clean after every use! The toothbrush head is bigger so I adjusted to that. I appreciate all the settings and love it comes with a travel case!

Poor battery

In less than a year the battery has died. It will charge up to 100% and then tanks to 0% after 3 seconds of brushing. Had our old one for over 20 years and was still running but the new one can’t last 20 months.

We're sorry to hear about this, Dayan. This certainly isn't what we expect especially since our iO Series 5 is backed by our limited 2-year warranty. It's possible this may be prevented in the future if it's stored in a dry area after use, but we'd like to collect some more details about this and share more about our warranty. Please call us at (800) 566-7252.

Loses charge too fast

I think I have a lemon. My toothbrush wont stay charged for a full week. I loved it when I first purchased it. Now it isnt worth it. I have to charge it every few days.

reply from TheOral-B-Team

We're sorry your brush isn't providing a full week of brushing between charges. We expect our brush to provide approximately 30 minutes of run time when fully charged, and our products go through many quality checks to ensure they perform reliably. We’re sorry if this isn’t the case. We’d like to provide a few troubleshooting tips that may help. Make sure the power outlet you are using is working as it should, and switched on if it is controlled by a power switch. Also, do not charge the toothbrush on a metal surface since the metal can interfere with the charging process. For maximum battery life, we recommend following this routine. (1) Fully charge the handle for the time recommended in the brush manual instructions. (2) Use the brush until it is completely discharged (or close to fully discharged). (3) Repeat. Do not store the brush on the charger after fully charging. We hope this helps you out! If you have need further help or have more questions, our Oral-B Team is standing by. Please give us a call at 1-800-566-7252 from 9AM - 6PM EST Monday - Friday.

Not working

The motor stop working after six months. There is no amount of charging that will get it to work again.
