    For whatever reason, I am geeky about buying high end electric toothbrushes. I decided to try this Oral B model after using a high end model made by another company. I really prefer the Oral B brush heads and the smart technology and app associated with this model are nothing short of amazing. I come away every time I use it feeling like a hygienist has just cleaned my teeth.

    I purchased this item as a replacement for a toothbrush that had worn out. We have the same model in another bathroom, so I was familiar with the product and wanted to enhance the brushing experience. This toothbrush has many features and I wanted access to those "bells and whistles" throughout my day. I use the Oral-B app to gauge my brushing.

    This is a really good electric toothbrush. Furthermore, I think it’s actually important to note that in a day and age where everything is going overboard with smart connectivity and millions of options and settings, this actually doesn’t do that. It’s as if someone high up said, “You can put modern features in, but at the end of the day, don’t forget it’s just a toothbrush.” And I appreciate that they didn’t try pander with useless gimmicks. This does, however, have 2 faults that are making me on the fence about returning. The first is the brush heads. I have this on the extra sensitive setting, and even got the sensitive brush heads. But it’s still not soft. Feels at least like a medium in a manual toothbrush. And my old model from at least 5 years ago had a replacement head that was very soft. So that came in as a real bummer. The other thing is also a feature in older ones that aren’t in this. I know it can be personal preference. But in the old one, the vibration would immediately stop entirely when you put too much pressure on it, and immediately resume once corrected. This keeps going, but does notify you by changing the ring at the top of the handle red. The old way was more of an interruption, and possibly a bit more annoying. But the annoyance of it is what helped curb the habit of brushing too hard. For those where that’s a big problem, the old way helped curb that habit pretty quickly. Overall, I would say you don’t need to spring for one this expensive, considering it doesn’t have any features that are a true wow factor. And is a bit limiting in areas.

    An ellecent tooth brush in combination with its app, really shows the areas you miss and maybe dont think to brush enough. You can even charge the toothbrush theough the case which makes my travleing aspect of my job that much easier.

    I read somewhere that using an Oral-B requires you to brush differently. I guess it’s something I couldn’t get right because I had more gum issues than ever before. I switched back to my previously used electric toothbrush (different brand) and my issues went away. Perhaps if someone has been using this brand and has the brushing techniques required for the Oral-B, this may be for you. Unfortunately the satisfaction guarantee period is too short for me to return it.
