Philips Sonicare2100 Power Toothbrush, Rechargeable Electric Toothbrush, White Mint, HX3661/04

I use this with my ultrasonic cleaner to clean gun, tools and hobby parts. Works wonders in my old hands. Battery charge lasts a long time and additional heads makes using different solvents easy to switch. Does a really good job on small, oddly-shaped parts.

My teeth love me for buying this product. Cheaper than the other stuff you can get and works really well.

I've tried Oral-B and they just don't compare to the Sonicare brand. My teeth feel cleaner and I prefer this style and size of brush head to the Oral-B round polisher style. Outside of cost, I don't know how anyone who uses an electric toothbrush could ever go back to manual. I've had to use one during an overnight business trip when I forgot my toothbrush and I might as well have used my finger. I even had my hygienist ask me if I used an electric brush because she could tell.

All things considered, the 2100 Series isn't a bad toothbrush. It cleans the teeth well.The handle is slim, lightweight and durable.There is a 2 minute timer and pacer built in.The battery is able to last about 18 days on a full charge and you have 2 different brushing intensity setting to choose from.There is no pressure sensor built-in which is a shame.The brush doesn't have lots of unnecessary extras included. In fact it lacks a 2 pin power adapter for the charging stand. The stand has a USB cable. You need to use your own USB to 2 pin adapter to connect to the wall.The 2100 is just a bit lost in the range of Sonicare brushes.I think the 1100 Series is better value for those on a budget and the 4100 Series is the best option if you can spend a bit more.The 1100 is cheaper and the only difference is the 2100 offers 2 brushing intensities rather than the 1 of the 1100.The 2100 has 31,000 bristle movements per minute, but the motor on the 4100 is configured differently to offer what feels like a better clean.Pros+ 2 intensity settings – choose between low and high power+ Timer and pacer encourage brushing for the recommended time+ Slim handle design – stylish & easy to keep clean+ USB charging stand makes it more convenient for someCons- No pressure sensor to alert you when brushing too hard- Fewer bristle movements than most other Sonicare brushes- USB charger makes it less convenient for some- Better value options exist

The battery life is amazing. Been using daily for over 2 weeks and not had to charge once. Doing the full recommended time twice a day. Love that the brush head is all one piece.

I have the much more expensive Philips Sonicare Diamond Clean toothbrush that my entire family uses on a daily basis so I bought this one to take with me when I travel. It's basically the same toothbrush as my Diamond Clean, but without the 4 extra cleaning modes and the cool, cup charger.Sonicare toothbrushes use ultrasound waves in addition to the brushing action to more effectively break up and remove plaque and it really does work. We've been using ultrasonic toothbrushes for a number of years now and have the healthy mouths to prove it. And since there is a direct link between gum disease and heart disease, healthy teeth and gums give you more than just a beautiful smile.If you've never used a Sonicare toothbrush before, you will notice immediately that it's a very vigorous cleaning. If you have sensitive teeth, it may even be uncomfortable at first. There is an Easy Start mode that gradually increases the power of the brushing action over a two week period to help you get used to it but for some folks, it still may be too much. Philips has other Sonicare models that have a Sensitive mode that are more comfortable for sensitive teeth. This model, however, has only the one, normal mode.There is an automatic 2 minute timer to ensure you brush for the full recommended 2 minutes, which is especially great for kids. It also alerts you every 30 seconds to switch to another quadrant of your mouth so you brush every area thoroughly.This model comes with one brush head. The brush heads should be replaced every 3 months, just like a manual toothbrush. The Philips brand brush heads are excellent but also pricey. I buy these, which fit perfectly and perform just as well, IMO. Standard Replacement Brush Heads for Philips Sonicare HX6014/13 ProResults (4, 8, 12 or 20 Pack) | Fits: Easyclean, DiamondClean, HealthyWhite, Flexcare [20 Pack]The charging base is very compact - great for limited counter space and for travel. There is a light on the toothbrush that flashes when charging and glows steady when charging is complete. When I travel, I always take my youngest son and I get about a week on a full charge with both of us using the toothbrush.I do not have sensitive teeth and I love the way it makes my teeth and gums feel. Additionally, it's fabulous for removing coffee and tea stains from your teeth. Plus, I like that one toothbrush can keep my whole family's teeth and gums healthy and all I need to do is order brush heads every few months.After purchasing the Blue/White color, I got this Guacamole color through Amazon Vine and and the Coral and Steel Blue colors as well. The Blue/White is the most neutral and should work in most any bathroom color scheme as it is primarily white. I'm using it for travel. The Guacamole is a lovely, light guacamole color that looks gorgeous in my spa themed bathroom that is green and bamboo. The Coral is a saturated, salmon pink color that would be great in a girl's bathroom. I put it in my daughter's white, gold and pink bathroom and it's definitely pretty enough to stay out on the counter. The Steel Blue is a medium blue with grayish undertones and looks great in my tiny, blue and white, beach themed bathroom. It's nice having all the colors to choose from so you can coordinate with your bathroom decor.The body of the toothbrush has a matte finish and it also has a textured area on the back so it's not slippery in wet hands. I'm also glad it doesn't have a rubberized finish because those always seem to get sticky after a year or so.If you want the Sonicare clean at an affordable price, this model is a nice choice.

I didn't think you could improve on the old one i had for a bunch of years but they did. It's lighter than the other one and has a 30 second timer to know when to change places. I also believe it's cleaning better too. Good job Sonicare
