When HX31420 is a relatively cheap once eggs model of Phillips, no frills or an especially sophisticated design. Nevertheless, we believe the brush with a very good performance and we can really recommend, especially if one is not quite conclusively whether you want to switch to sound cleaning in general or not.
The toothbrush is loaded quickly, the essays can be attach easily and change, it fits comfortably in your hand and is rather handy. The design is simple and the product does a carefully crafted impression. The charging station is as small as, for example, in a normal Oral B.
One can not choose choose between different settings or programs in this brush model, only it's a timer. A battery gauge is not found, but simply has to estimate when a charge is needed.
Since we use a sonic toothbrush is no longer necessary according to our dentist a professional dental cleaning. Tartar is no longer found since.
We are completely satisfied and you will give a strong buy recommendation !!!
