I worried my FoamMaster for research in paint care area.
He was quite often praised times, but I can associate myself with this only slightly.
The idea (auto) is of course good, work in itself quite well. You have to employ a little to get a reasonable foam for a "pre-wash" course with its products. This can be achieved quite so for about 5 seconds when wheel to wheel and back into ca.30cm wide ... Then is then directly back in fashion pumps, dda he begins by at least 5 seconds to shoot the outside edges as thick beam and the remainder decreases significantly. Spraying dam in principle thick lines with significantly less foam in between, at the end of the lines then act like shaving cream, thick halt.
This can get a little more in the grid with the safe dosage and other use, but it looks in the advertising image alone is much better, maybe even a little Photoshopped :)
Overall, however, can use a good alternative to a foam lance, which indeed now not everyone has or at home.
Defects / Negative:
The container may be cleaned for normal home use, shower / window, etc. absolutely sufficient. However, anyone who is planning to make his car so access to the MUST 100 Euro variant with a larger volume, pumping stupid and dimwitted :) The effective amount of liquid is not very high, since one also needs space for air.
Material is up to the container to be rather modest, it seems to me ... The blue knob on the pump rod has broken me in simple pump, then had him individually in his hand.
Added to this comes still that without serious external influences the peak has passed by the pressure relief valve, which I can no longer pull out with the fingers for venting this ...
These two points I think, no matter for what use, very disappointing! For the price to get such a quality, well .... So he has survived three car washes, very very sad and disappointing.
