Review: 10/10 Recommend + Getting my entire family this toothbrush - I never write reviews but I’m making time for this one!! First off I spent hours researching and watching reviews on “the best electric toothbrush”. And it lead me to this one. It’s not too expensive like the diamond clean being $300+- it’s right in the middle for the price point and looks good, not too outdated and comes with a travel case, also it has all the features I’d really need. This is my first electric toothbrush coming from your regular target brand toothbrush’s ranging from $5-$20. What made me think of getting this over an oral B was the “sonic technology” which seems to be specific to the Phillips Sonicare brand, whereas oral b and others just rotate or whatever. Overall though it’s the best toothbrush I’ve ever owned and I’ll probably never go back to a regular toothbrush. My first concerns were reading other reviews that it broke in a year or 2 because of whatever faulty reason. But honestly if it breaks I’ll probably just get another one again because it’s worth it !! The clean is next level compared to a regular toothbrush and it’s a clean you’ll never experience without one of these toothbrushes. Once you realize what the vibrations mean you don’t need to use the app too, I never use the app and I know I’m gonna get a perfect clean each brush. As sad as it is to say but I look forward to brushing my teeth now every day knowing how clean and perfect my teeth are gonna feel afterwards lol. If you’re worried about the money then these types of toothbrushes aren’t for you. But if you can look past the price it’s 100% worth it.
Review: The best toothbrush - I bought a pink one and a blue one for my son, I recommend it. It is very important to take care of the health of your teeth. It cleans well, the only drawback is the high price.
