Philips Sonicare 2100 Series Electric Toothbrush - Sonic Toothbrush with Advanced Sonic Technology, Two Intensity Settings, Smartimer & Quadpacer, White, Model HX3661/04

This toothbrush delivers exactly what I was hoping for — powerful cleaning without unnecessary features. It’s easy to use, with a sleek and lightweight design that feels good in the hand. The vibrations are strong enough to give that dentist-clean feeling, and the built-in timer helps ensure a full, even brushing every time. The charging base is compact, and the battery lasts a long time between charges. I also appreciate how quiet it is during use. Replacement heads are simple to swap out, and everything about it just feels well-made. Overall, it’s a solid electric toothbrush that does its job really well — no complaints at all. Highly recommend to anyone switching from manual brushing or looking for a dependable upgrade.

Great electric toothbrush! Love the neutral white color and it holds a charge for weeks. Teeth and gums feel very clean after each use. Easy to hold and maneuver and I like the fact that it lets me know if I am pressing too hard. Very pleased with this purchase.

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

Phillips Sonicare 2100 Power Toothbrush works as promised. Lightweight and easy to use. The charge lasts a long time which is a nice feature. Replacing the heads can be expensive but I think I will opt for the Phillips genuine ones next time as trying to use generic ones seemed to harsher on my teeth. Overall I am satisfied with product.

Exactly as expected, great condition. The batter lasts for weeks! Don't leave it plugged in, let it air dry and recharge maybe once ever week.

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.

I love this! Great value for the money. You can feel that it’s working

I thought I'd come by and warn folks about these electric toothbrushes.See, Sonicare is a very famous brand of dental hygiene products, and the technology used here is proven to be very effective. Rapid gentle motion of a set of soft fibers-- you know. We all get it.So I've been using Philips Sonicare for many years, and I'm certain that my oral health has benefitted from that.The trouble is, Philips can't build one of these that lasts more than half a year. I keep having to replace the units because the power switch fails. One after another. The last purchase was 10 April. That's right-- just over three months ago.The rubbery membrane covering the power switch has cracked open and water has leaked into the switch, and the switch has failed. It either won't come on, or if it does finally come on, I can't then turn it off.Can you imagine? In the year 2024? Philips can't design and manufacture a power switch on a toothbrush that lasts more than a few months?Well, of course I know the answer.It's supposed to fail, and I know it.It's planned obsolescence, and I know it.I wanted to let you all know. These are very worthwhile products from the perspective of one's oral health. But the company is ripping you off intentionally.I'm at this moment going to another brand and I will not buy a Philips product of any kind again. It's a matter of principle to me.I won't. I refuse to bow down to these greedy and wasteful and arrogant corporations who try to manipulate me into more sales by intentionally manufacturing failure into their products.They are intentionally trying to arrange for us to develop habitual purchasing of their products, in repetitive cycles, again and again, and they're attempting to teach us to accept miserable quality as inevitable and only customary.I realize that this has become par for the course, and to many people it doesn't matter-- they're not bothered by constantly buying a new item, over and over and over again.I really don't care. I'm a discriminating and conscientious and logical person, and I refuse to participate in this kind of idiocy.
