I am disappointed anyway. (I've already had one that was great that I never have the pay n) so there was a lot better same cell, I do not find it very efficient to the extent that it is necessary to board lot times and the result is not terrible. it is easy to grip, easy to empty tank, to clean too. s not the batteries wear out quickly, but at the same time it is not ultra dynamic power. I do not have it returned because the box was stuffed with scotch, and therefore the take off to test the device. the box is completely torn, I haven ^ m not me back.
