No difficulty to avail of this brush: a single button to turn it on. A "professional" timer (lol) reminds every 30 seconds to change dental quadrant. This timer is not unanimous in the family: some have found useful, some less and would have preferred it to be disengaged.
The pressure sensor is a plus although we must be good students because it is rarely triggered. But for the test, I put the pressure and yes, it works. A beep to indicate that it is triggered would be a plus.
The load is long since charging takes 20 hours to 30 minutes (what makes a person a week) brushing.
The weight of the brush is correct, it takes up little space because its base is reduced (too much for my taste because once the brush above, all is not stable at 100%) short, it would have been almost perfect at take a trip if Oral-B had provided a transport shell. There he must appeal to the D system, for example by keeping the packing box.
This lack of hull is my only real regret.
The "only" 4 * takes account of the fact that the Oral-B Electric Toothbrush Rechargeable Trizone 5000, has currently sold 75 euros a quality / price higher
/ * Added 12.17.2014: the price the Trizone 5000 having increased significantly, I spend my rating to 5 * /
