The Philips Sonicare DiamondClean Rechargeable Electric Toothbrush is a very popular model among owners, thanks to its sleek design and excellent performance. There are few, if any, reliability issues with this model, and it's lightweight and attractive to display on a vanity top. Owners do, however, lament the lack of a UV sanitizer, and several point out that less expensive models are capable of the same results (admittedly, with less style).
Top of the line cleaning with a price tag to match. User reviews for the Philips Sonicare DiamondClean Rechargeable Electric Toothbrush are almost universally glowing. Users say their teeth feel "squeaky clean" and they're getting the thumbs-up from the dentist as well. Professional reviews are equally positive, but many quote performance results from Philips press materials, so it's difficult to say whether any of these are based on first-hand experience. One caveat that comes up frequently from users is that the handle of the DiamondClean is the same as the less expensive Flexcare, and that it's really no more powerful. It does have different brush heads, though, which also fit older and cheaper Sonicare models.
Beautiful design is a key selling point. One reviewer puts it best in likening the Philips Sonicare DiamondClean to an Apple product. Owners generally find the brush sleek, lightweight and easy to use. They love the backlit buttons, though one owner points out that they can be difficult to read. This is also challenging because the buttons are flat, potentially making them difficult to find for sleep-addled brains.
Settings, timers and accessories all add value. Owners and pros alike love the bells and whistles of the Philips Sonicare DiamondClean. Specifically, reviewers point out the five cleaning settings (one two-minute setting, plus additional one-minute specialty settings for whitening or other problem areas). They also love the water-glass-charging-base combo, which is far less unsightly than the usual electric toothbrush charging stand. Like other top-of-the-line brushes, this model includes a two-minute timer plus a "Quadpacer" to ensure even brushing. Finally, the DiamondClean also comes with a USB-charging travel case to take on the road.
Durable but high maintenance costs. Many owners applaud the Sonicare brand in general for its durability, but few specifically praise the Philips Sonicare DiamondClean, likely because it's a relatively new model. That said, editors didn't find any reports of durability issues. However, replacement brush heads are comparably very expensive -- $25 and up for just two (about twice the price of Oral-B brush heads). Surprisingly, reviewers didn't mention this as a concern.
More than 650 Amazon.com reviewers give the Philips Sonicare DiamondClean an average rating of 4.4 out of 5 stars. Reviewers particularly praise the sleek and attractive design; one likens it Apple's product designs. Several, however, complain about the lack of UV sanitizer, which was available on earlier Flexcare models. Some reviewers allow that other cheaper brushes work just as well -- and the specs for the handle are in fact the same as the Flexcare+.
