    • Great toothbrush if you know how to use it, it can be repaired!
Size: 1 Count (Pack of 1) Color: New Black
This is the third one I have owned. I read the reviews and it seems hit or miss. After 10 plus years of using the black diamond here is what I can tell you. If you press too hard (apply to much pressure) while brushing it causes slop in the sonic arm that the brush head engages. This arm has a gap set inside the handle and is held in place by a small screw. You do not need to push at all on the brush. If you do and the arm is wobbly and you don't feel the sonic motion, it can be fixed pretty quick. There are vids on YT that show you how to reset the gap and tighten the screw step by step, note use some locktite when reapplying the screw. There are also vids that show you how to replace the battery and actual upgrade it!! On the first 2 I bought, I applied too much pressure and was frustrated with the toothbrush. So I took it apart before trashing them and stumbled onto how to repair the $300 toothbrush. Phillips was of no help either. So you may ask why did I continue to purchase and repair the black diamond? Fair enough! Its because for 10 plus years I have had consecutively perfect dental appointments! Everyone of them! Very minimal cleaning, in and out in about 30-40 mins each visit and told keep doing what you’re doing. So its pricy, you need to know how to use it properly, Phillips customer service is ehhh, can be repaired and most importantly it WORKS! All three are still charging and working flawlessly! I have one for home, one for travel and a back up. Had I known you could repair them I would not have bought the second one. This one was on sale and ridiculously priced so I bought it. ... show more

    • Spend once, cry once - get quality and this is it
Size: 1 Count (Pack of 1) Color: New Gray
I tried several cheaper sonic toothbrushes and hated them...they rattled my head even on low. Many had tiny / too small toothbrush heads. Then I sprang for this baby - well worth it! I haven't even gotten to the app or the deep cleaning, etc. But just the basic toothbrush is amazing! I keep it on low for now...which is fine for me and I can really feel the cleanliness when I'm done! I wanted this one also because it has a warning if you are pushing too hard. I'm also pleasantly surprised by the tongue cleaner head / program. All in all, it works really well. And - if you get extra brush heads, no reason you can't share this with someone else in your home. ... show more

    • Beautiful Investment to Myself
Size: 1 Count (Pack of 1) Color: New Rose Gold
I had always used a manual toothbrush until my dentist recommended I get an electric toothbrush due to some gum disease onset. I asked the dental assistant which they recommended and she said everyone on their office has the Phillips SonicCare line. I immediately bought the 4100 a few months ago while I did more research and the 4100 did a good job. I’m Amazon Day when it went on sale, I upgraded to the 9500 because of the gum health and white teeth features and it appeared to be much better quality. This toothbrush far exceeded my expectations! It’s powerful and amazing! The different brushes are so nice too. It feels luxurious. It cleans and brushes much different than the 4100 model. I love the travel case and will use that. The glass to charge it in is really cool and pretty. It’s beautiful! While not cheap, I got a great deal and look forward to my next dentist visit. I’m confident it’s making a big difference and is an investment in my oral health and because gum health affects other health conditions, this is a great investment and gift to myself overall. Worth every penny. ... show more

    • Don't Waste Your Money! It'll break in 10-14 Months.
Size: 1 Count (Pack of 1) Color: New Black
I've tried two different brushes of this model and had the same issue with both of them. Each time the brush broke after about a year's worth of use. The handle vibrates but the brush stem (the metal that holds the brush head) does not because it's detached from the drive shaft. There are several flaws with the design that could cause this to happen: 1. The metal drive shaft inside the handle is poorly constructed. It loosens over time and eventually detaches from stem holding the bristles. 2. The Internal adhesive or press-fit joints weaken over time and cause the brush stem to detach. 3. Moisture gets into the brush (likely through the top or near the buttons and eventually weakens the joint with the drive shaft. 4. The parts just wear out. Any one of these makes the brush unusable (unless you don't mind paying $200 for a manually operated toothbrush). Sure, you can send it back for a warranty repair (two-year warranty), but who wants to request warranty repairs (and be without your toothbrush while that's happening) multiple times in two years. No one expects a brush to last forever, but 10-14 months is unacceptable for such a pricy product! You're better off buying an Oral B iO series brush. ... show more

    • BEST VALUE
Size: 1 Count (Pack of 1) Color: New Rose Gold
BEST IN ITS OWN CLASS - By far the best electric toothbrush SONICARE has offered and it's well worth the investment. The 9500 Rose Gold model has a pearlized white handle, its durable and looks great. The lowest vibrational setting great for sensitive gums and an incredible improvement over previous models, so no need to buy a sensitive care brush. The higher settings are also improved and well calibrated and doesn't have that grinding sensation attributed to the more economic models I've purchased in the past. The brushes are also improved and this model comes with 3 brushes in the box, all with dust covers, (not pictured in the product description): Teeth whitening and plaque removal, Gum care, and Tongue care. This is the only model with the Tongue Care mode and the special brush attachment. The Diamond Clean Smart 9900 costs $100 more and doesn't include this mode and the special brush. The battery life is good - about 12 days. This model doesn't include a case for the brushes, but they easily fit into the glass charger along with the handle. The app syncs easily to blue tooth and set up was easy. SONICARE DIAMOND CLEAN SMART 9000 gets 5 Stars!!! ... show more

    • Best toothbrush available
Size: 1 Count (Pack of 1) Color: New Pink
Great product at a great prime day price. Make sure you register it because these have a tendency to break at the base of the tooth brush applicator. My last two did exactly that, after a couple years. That said- my gums and teeth are so much better and cleaner because of these. I will continue to buy them. ... show more
