Old one:

New One
Results (used about 1 container worth of mix of 50ml car wash and the rest warm water)
Before:
During (yes it is a different car):
After:
A few minutes later (leave on to soak):
Rinsed off:
Beefs:
It is difficult to adjust the amount of mix that is sucked up (the valve is either on or off)
The knob to adjust the amount of air (to produce the foam) is very sensitive, hence the amount of foam made is nothing or equivalent to AFFF

More expensive than the one it replaces
Pluses:
It has its own built in regulator!
Does what it says it will, make heaps of foam.
Worth the extra cost as the old one was difficult to get set up.
The final job after a cut and polish:
