    • Treat yourself! I promise you will NOT be disappointed!
Color: Lunar Blue
First off let me say that after growing up in the 90's the thought of spending $300 on a toothbrush is absolutely ridiculous - until I bought one. The day I received it in the mail, I couldn't wait to get it out and use it for the first time. I had never used a toothbrush like this one before. I usually used the cheaper $10.00 battery powered toothbrushes that you throw away once its depleted. The directions recommend you to let it charge for a full 24 hours prior to using it - however in my case I had already thrown my toothbrush in the trash, and the excitement of the product forced me to use it immediately. When I opened up the package, I was quite surprised of the quality of not only the packing, but the classy display of the contents and the quality of the materials. I picked the toothbrush up - Wow! Never thought I'd be saying this, but "What a beautiful toothbrush" is exactly what I said. The different brush heads are packaged nicely in their separate "baggies". I got the charging base and glass cup out of the packaging, and set it up like the directions say. I set my toothbrush in it and voila! The brush beeps/vibrates twice to let me know it is charging. The battery indicator blinks when the unit is charging. Just like the description says, you get several brush heads: Whitening, Clean/Deep Clean, Gum Care, and one tongue brush. Each brush head is marked on the front of the neck which one it is (C - For Clean) (W - for whitening) and (G - for gum care). If you still aren't sure you can always just place the brush head on the toothbrush and it'll "magically" tell you which one you're planning to use. Another neat thing I noticed is each brush head (that comes in the package) has a microchip, so not only does the toothbrush know which one you're using, it also knows the best intensity and vibration pattern to use which cooresponds with each head. Granted you can change it up anytime you like during the process (brush cycle prior to brushing, intensity while you're brushing), but I thought it was an ingenious idea for it to be this smart. I got the app downloaded, set up my profile, and was ready to brush. I picked the toothbrush up out of the glass - immediately it lights up. I place the "Clean" brush head on it, and the app automatically switches to the "clean" mode and opens up the brush screen - all without me lifting a finger (granted this only works if the app is already open prior to picking up the brush or turning it on). So I turn it on, the app starts telling me the parts of my mouth to brush, and I go to work. The feeling of using this toothbrush vs what I was used to definitely was an awkward feeling - yet it was quite pleasant. I finish the cycle, and then the app proceeds to tell me areas of my mouth I didn't brush as good. It says "Turn on your brush to touch up". I push the Botton and brush exactly where it tells me to. Once the cycle is finished it tells me I did a fabulous job. It reminds me to rinse, floss, and use mouthwash. I've been using this toothbrush for almost a week now and I can already say I'm in love with this thing. My teeth feel as if I've just left the dentist's office. They're already several shades whiter. I'm in love! I will never own anything else other than this toothbrush. ... show more

    • Excellent for a never experienced user
Color: Lunar Blue
I was a non-believer in electric brushes. I never thought they would do very good compared to just using a regular toothbrush. I didn’t know what to buy so I figured that I would take a chance and go all out. If I wanted one, I wanted to ensure I got a good one for a good experience of how it should be. And not settling for something cheap that would continue keeping me a non-believer. I love this brush. While I have no experienced other brands or types, I know for sure that it is doing a darn good job of cleaning my teeth. Feels clean, feels good, and does not feel uncomfortable at all. My first experience with it was during travel. The case is excellent and convenient with a USB to charge and can be secured in the case. The standard charger for home use is very nice and the glass is very sturdy (if I break it, it’s because I got careless with it). Battery life seems to be more than enough to go for quite a while without a charge. But that should not be an issue anyway with having 2 ways to charge it. The app itself is quite simple (kind of disappointing between what I expected and what it does). How it works is that the app defines the range of teeth in quadrants. Top left, bottom right, inner, outer, etc. it does not know which tooth you are currently brushing or for that matter, which quadrant you are brushing. It merely knows whether you are brushing the inner or outer part of your teeth (the handle seems to know if the brush is on the inner or outer part of your teeth). So while not what I expected, it’s still effective enough to ensure you have fully brushed all areas of your teeth. But the app cannot determine if you are brushing the left or right side of your mouth. It is expecting that you are following it’s instruction. You don’t need to use the app. But I would recommend starting with it. Because depending on the setting, the handle gives an audible buzz that tells you to switch areas. And if you do not know what or where that means you should go next to brush, you cannot define what it is telling you to do. It even recommends which brush type to use based on your settings. Overall though, my first experience with my first electric brush being this particular brand and model has changed my way of brushing. And unless something goes wrong between now and next few years or so using it, I’m sold on this and do not even need to try another. ... show more

I’ve already lost most of my teeth due to medications and genetics. I’m trying to keep my remaining teeth as healthy as possible while still being gentle but thorough on my very expensive implants. This is one of the best Sonic toothbrushes I’ve ever owned. It does exactly what I need it to, doesn’t make my gums bleed like others have, and has so many more features that make it a worthwhile purchase. The charger is cute/stylish while still being useful by adding a glass cup to rinse your mouth with. The case is not just sleek and gorgeous, but is high quality and even charges via a USB port that is safely tucked away. No need to bring a bulky charger with me anymore. Now for the reason I chose this one: (it wasn’t just the nice color) it has an app that shows you where you need to focus to get a better clean and how well you are doing. These replacement heads are a bit more expensive, but after paying so much for my implants, I find this to be well worth it. I’m shown how long I should brush which sections, if I’m missing an area in my mouth, if I’m brushing too hard. Over all, if you care about your teeth and don’t want to end up with a mouth full of cavities and fillings or worse: dentures, invest in this toothbrush. ... show more
