I foolishly thought that would be enough to try the Shewee once in the shower, the toilet and once home to be a pro .... we are off the mark! So either I'm damn bad (you never know ...) it must not drive badly to get there! Anyway, the idea of not having to do stunts in the public toilets seduced me so I'll persevere !!! I specify that the box is still quite large, no way to put it in a pocket discreetly !!! This is closer to the size of a TV remote control as a mobile phone !!! I think "extension" is really essential to not having full shoes. I am curious to try other more discrete models to see if they suit me but considering the price I will not make a collection !!!!!
