The first brush was made after each use directly back to the charging station, which should be no problem for modern batteries. The second brush was then off for safety's sake and to use time without recharging until the battery was empty, what should be a problem any more, in fact quite the opposite. But so that the battery was then probably certainly not cope.
Frankly, I do not believe in something in coincidences and therefore suspect that the underreporting of the problem is substantial higher than indicated by the reviews here. I think that a lot of the reviews in a timely manner arises after purchase, while also nothing to say, and many people just do not know that you can also change reviews again later. And as long as the brush work, she was lt. My wife also really great.
Perhaps there is also a lot of users (inside) that do not really use the brush regularly. My wife used it daily.
Given the still relatively high price and the extremely negative long-term experience a renewed buying this model is now of course no longer in question. The FC 45 by Beurer for example costs 20, - only about 1/6 of the price and has thereby even 3-year warranty has taken only 2 as Philips (!). We have the Beurer yet, but let's be honest - the brush should just turn (not oscillate like many other models), and if it really soo are there big differences ... Well, I am now, unfortunately only one man and can perhaps not really judge. ;) From the durability ago they can definitely do not ever be worse if even 3-year warranty offered. Not to mention that I can buy from the part has 6 pieces in a row before I have spent the same money as for Visapure.
Once you can buy from Philips have no TV (by far the worst and fehlerbehaftetste software of all major brand suppliers), the cosmetics of the Dutch are burned for me because of that experience now. My electric shaver is fortunately still, but will have been the last of Philips.
