The great quality of 6400, I have stated. To summarize, this is a cheap epilator which is right on target, and does it well.
The 6423 has the same qualities. If you are looking epilator with 36 options, magical painkiller formulas, go your way.
There have any February 2 epilation speeds. The epilation head comes off easily by pressing the sides, and is recovering well.
The 6400 default was not really, except that offer only head "basic" unusable on sensitive areas (armpits), except to have a particular taste for torture sessions. And of course the price was filiaire, so not usable in the shower (for those interested), but you could flush his head once detached from the body of the epilator.
Ditto for 6423 (filiaire not usable in the shower, washable) except that in addition offers a shaving head, intended to too sensitive areas like armpits waxing.
Obviously, since this is more of waxing shaving but it feels absolutely nothing. By cons, there will be inconvenience of shaving ... (that hair will grow back faster and thicker / thick).
As another advantage, there is reduced congestion for transport due to the net decrease in the size of the power cord (but good in 2 cases, the size is small).
There are no storage pocket, unlike what is shown in the drawings of the plug (do not rely on it, but read the chart below to see what is actually provided with your model )
Total: simple epilator, inexpensive, efficient, fast, easy to transport and clean, which has the advantage of providing a shaving head for sensitive areas. If it is not useful to you, then you will turn to the models below, about 10-15 cherquand even less. If you are looking epilator with accessories, one must go upmarket.
This epilator or its little brother remain in any case very interesting travel epilators, compact and inexpensive.
