About its features
Caveat: I received this at a discount to evaluate and provide an unbiased review<br /><br />I feel really badly to drop my rating from a five star (see below) to a 3 star, because the unit stopped working after about 3 months. Until then, it worked great - I was able to use it for close to 2 months without charging it.  I really liked it. Unfortunately, it stopped working.  May well be my fault, I may have been pressing the activation button too hard - I'm type A and noticed I was breaking pens because I pressed so hard. Even if that was the problem, I felt the unit should accommodate people like me. I asked the person who contacted me about their warrantee policy - she replied she didn't know since no one had ever told her it stopped working!<br /><br />That said, the Beiwin Sonicare is a really nice product. It may not be right for everyone, but it has advantages over the two year-old Philips Sonicare that I had been using and possible disadvantages.  For the record, I haven't checked Philips' subsequent products.<br /><br />I prefer it to my two-year old Philips toothbrush.  Some users may find it particularly useful, such as travelers and some people with hand/wrist disorders such as arthritis for reasons below.<br /><br />The manufacturer, Beiwin, listed these features in their Sonic toothbrush:<br /> -  3 brushing modes ( low, massage and high) with a two-minute timer.<br /> -  Sonic technology delivers up to 42,000 brush strokes per minute.<br /> -  Magnetic inductive charging provides 3.5 hours fast charging  and stays charged for 60 days when brushing twice a day.<br /><br />Pros<br /><br />1. Wow, the charge is very impressive.  I used it for a couple of weeks now and I haven't charged it once. As mentioned above, it should last a couple of months brushing 2x/day  without charging.  That's way more than my old brush.<br /><br />2.  It is more streamlined, more narrow and lighter in weight than the Philips I was using,<br /><br />  The base of the Beiwin Sonicare measures 1&#34;L  x 1&#34;W, while the Philips Sonicare measures 1 5/16&#34;L and 1 1/16&#34; W.<br /><br />3.  I like the three brush mode settings.  I tend to go with light setting.<br /><br />4.  I did &#34;off the cuff&#34; testing with three people, who thought that the vibration of the Beiwin seemed to be a bit less noticeable than my former one.<br /><br />5. The charger is quite different than others I've used.<br /><br />Instead of a cord, it takes a standard removable micro-usb cord.  I find connecting the cord on my Philips toothbrush annoying as the charger keeps on itself.  And it's easier to deal with if your dog chews the wire (unplugged).<br /><br />The toothbrush charger sits on a very small base.  Maybe the size of a Susan B Anthony half dollar.  No problem sticking it in your wallet when you're on the road.  The charger pulls the toothbrush to its base with magnets.  I<br /><br />6.  The product is quite inexpensive.<br /><br />Sidebar:<br /><br />1.  The shape of the bristle head is a bit rounder than the Philips, and the bristles have about the same amount of hardness.  A review of the literature on toothbrush design by Hayasaki (cite below), which concluded that research suggests the shape of the head is not as important as the diameter of the filament - thinner filaments feel softer and more flexible, but thicker bristles clean more effectively.  So both toothbrushes should equate in shape and hardness of the filaments, though users may prefer different shapes of the head.<br /><br />Cons:<br /><br />1.  And this is a big con - it looks like they intend to sell the brushes as separate items at some point but currently Bewin doesn't seem to be providing them yet.  I'll change my rating if I notice they are available.<br /><br />There is no reference on this page as to what buyers are supposed to do, other than buying another set.<br /><br />The brushes on my Philips toothbrush don't fit on the Bewin and I don't see a reference to what wethey currently they aren't selling<br /><br />2. It doesn't include a travel case.  Not a problem for me since the Philips case fits it fine.<br /><br />3.  It doesn't include a USB converter if you just want to plug it in.<br /><br />4.  As I mentioned, although it's not an issue for me, it is easier to wobble the toothbrush on its base.<br /><br />Citation:<br /><br />Hayasaki, H., Saitoh, I., Nakakura-Ohshima, K., Hanasaki, M., Nogami, Y., Nakajima, T., . . .
