Philips isn't messing around with this electric toothbrush, which promises to remove up to seven times more plaque than a manual toothbrush. It offers two intensities and a pressure sensor to help you get that just-right level of clean.
This toothbrush hasn't been priced this low since last December, giving you another chance to save at a rock-bottom price — at least, until that savings disappears for another year. At just $30, Philips' 4100 is significantly cheaper than much of the competition.
Why do I need this?
A Philips Sonicare toothbrush is really a no-brainer. First of all it’s suitable for anyone, and that includes you. And of all electric toothbrush brands out there, Philips Sonicare is the one most recommended by dentists. In fact, brushing with the Philips Sonicare 4100 Electric Toothbrush is truly like going to the dental hygienist for a cleaning every single day. You know that silky smooth feeling when you run your tongue across your teeth after a professional deep-clean? That, but on demand.
This Philips Sonicare model has me particularly intrigued. It doesn’t just remove more plaque than a manual toothbrush — it removes seven times more plaque. The device has a two-minute timer, which lets you know you’re brushing according to the ADA’s recommendations. Studies show that people who brush for two minutes remove 41% of plaque — compare that to folks who brush for one minute and remove 27% of plaque.
The Philips Sonicare 4100 Electric Toothbrush also has a pressure sensor that lets you know when you’re brushing too hard, a feature that reminds you it’s time to replace the brush head and a battery indicator that lets you know it’s time to recharge — but the battery lasts 14 days!
So many features, so little money. I can hardly believe Amazon is selling this little powerhouse for $30, but hey, that's Cyber Monday (well, Tuesday) for ya!
What reviewers say
Let’s check in with those 22,000+ customers who are absolutely in love with their Philips Sonicare 4100 electric toothbrushes.
“I got this one to replace my 7 year old Sonicare and the difference is amazing," said one fan. "Even on the low power setting, it has a lot more oomph, the bristle is much stiffer and somehow cleans a lot better, and I love the feature where the head starts vibrating if you press too hard. My dentist had told me in the past that I brush my teeth too hard, so this is a great feature."
A fellow happy brusher raved about the "great clean" they got. "It really does clean SO much better than the moving bristles on the battery powered one," they said. "Mouth feels better after brushing and gingivitis has really improved. Battery life is excellent."
This sale price won't last: Grab your own Philips Sonicare 4100 at a sweet discount while you still can.

Aside from their fab price (40% off!), we love the real-time power readout on the front of the case of these earbuds, making it so much easier than pulling out your phone and swiping to find out how much charge is left. The top number shows how much juice is in the case, while the two smaller indicators show readings for each bud. Pretty smart! But that's not their only innovative feature: These buds have everything you'd expect in a quality pair. On-ear controls let you answer calls, skip songs and activate Siri.

This No. 1 bestselling, TikTok-famous compact carpet cleaner packs a punch, especially considering it weighs less than 10 pounds! Its powerful suction can be used to remove stains not just from rugs, but furniture and even car upholstery, too. Plus, it comes with a self-cleaning hose tool and a bottle of Bissell's Spot & Stain with Febreeze. We haven't seen this viral cleaner priced much lower than it currently is in years (it was only a few bucks cheaper back in July for Prime Day) — and when you consider how much money it'll save you in professional cleaning bills (and replacement furniture), it'll pay for itself in just a few uses.
At just about half a pound, this topseller is like an ultra-lightweight extension of your arm — and what it lacks in heft, it certainly makes up for in dexterity.

The durable metal rod extends as far as 32 inches for easy reaching and folds down for space-saving storage when not in use. Its rubber claws ensure a secure hold, and its grips are also equipped with magnets for lifting metallic items small and large.

With its 6-quart capacity, this gorgeous air fryer can hold enough food for five to seven people, yet its small footprint won't take up too much space on your counter. Its patent-pending TurboCrisp technology helps ensure quick, even cooking with that crunch factor we all crave (though you'll be able to cook with as much as 75% less fat than deep-frying). The user-friendly touchscreen lights up while in use and features time and temperature settings (from 90-400 degrees Fahrenheit), as well as four functions: Air Fry, Roast, Reheat and Dehydrate, the latter of which is a cool feature that isn't always included with air fryers.
