Philips SonicareProtectiveClean 6100 Rechargeable Electric Toothbrush, with Pressure Sensor, 3 Cleaning Modes, SmarTimer and QuadPacer, 14-Day Battery Life, Travel Case, White, Model HX6877/21

My daughter came in and told me her toothbrush failed. I looked to see if I'd purchased an extended warranty, but none was available. As I looked at the $130-179 replacements, I noticed some reviews saying the Amazon warranty was only a few months--but that CVS would've sent a free replacment. I found the e-mail confirmation of registering from 27 months ago (there is a 30-month extended warranty included--at least in our case.)I contacted the chat line literally 6 minutes before closing on this Friday night--w/o much hope. Not only was "Aida Mae" impeccable in her service, but she led me through a few simple tests, and then determined that a free replacement needed to be sent out -- which was summarily-processed. There was no charge whatsoever.The tests involved de-activating the "Quick Start" feature. While the unit is charging, hold down the Power button for a few seconds until you hear a few beeps. The second test is asking whether the unit had been charged for 24 hours since the problem started (yes.) Next, I was asked to try the different cleaning modes, and to go through the 3 intensity levels--same result. Lastly, I was asked to change to a different brush head (still no different.)Like others, I've used Sonicare brushes for decades. My whole family except my 10 year-old uses them -- he has a competing, simpler brand, but will "graduate" to a Sonicare in due time. This 6100 model looks and acts identically to the 6500 models my wife and I use -- except ours came with the fancy travel case (which I've never used beyond just testing it out.) The 6100 works in the travel case, too.The sense of cleanliness is second-to-none. We use the C3 whitening heads on all of ours. Combined with a Wal-Mart pre-brush rinse, a water flosser, and Crest Clinical rinse, I get excellent dental reviews. When I use the Crest 3D White Professional Effects No Slip Whitestrips, my dental hygienist JUMPS BACK at the brilliance! This experience is based on the 6500, but I can't see any visual, mechanical, or operational difference with the 6100.

This toothbrush is great! I love it. My first experience with an electric toothbrush was an oral b one I bought at the grocery store because it was on sale. I actually really liked it and had it for years. My husband was talked into buying a different kind by our dentist after he had a root canal. He was a bit loopy so agreed to buy two of them and they were terrible. But he had already thrown our other ones out so this is what we were left with. I hated it but didn’t want to buy another one and waste the money. It died after every use. It was just the worst. I think it was called pro sys. I wouldn’t recommend them. Anyway I got off track. This Philips toothbrush is great. My teeth feel very clean after brushing. I like the different mode options, different brush head options and best of all the battery lasts so long! I went on a weekend trip with this toothbrush and didn’t bring my charger. I didn’t need it. Then I didn’t charge it for about 2 weeks after getting home and it was still working fine all that time! Finally it let me know it was time to charge it but I was impressed with how long the battery lasted. It will also alert you when it’s time to change the brush head. If you’re looking for a efficient toothbrush and not worried about apps and other bells and whistles so brushes come with this is a perfect choice.

I have never been more in love with brushing my teeth! Toothbrush was a recommendation from dentist since I have some gum recession. I still don't know how to use all the settings but it's not super loud, easy one the gums, and handle is long. I swear it glides over my teeth! Never thought I would feel this way about a toothbrush and thought the hype was over nothing but 10/10!

The media could not be loaded. I upgraded from the 4100 to the 6100 and immediately noticed the stronger vibration. It doesn’t lose power when you apply pressure, so the clean feels deeper and more effective. That alone makes it worth the upgrade.I also love that the charger plugs directly into the wall—no USB block needed. Just simpler.Only small issue is the gap between the brush head and base—water can sit there if you don’t wipe it down. But the overall performance is far better than the lower models.If you want a no-nonsense, powerful brush that actually cleans well, this is it.
