Yes I know, but it does depend on what's tested and under what conditions.
It would be pretty difficult to stage that comprehensively.

It rather reminds me of those in line magnetic devices that attract sludge
particles out of the water rather than their being deposited in radiators.

Mr Whetstone's invention undoubtedly works to remove air from CH water.

However, like the magnetic thing, it's addressing the issue in the wrong
way - i.e. fixing the symptom, not the cause. It's reasonable to have
an air separator during filling and for a few days afterwards white the
dissolved air is driven from the water. After that, it shouldn't be
needed. If air is still in the system, it has to be entering somewhere,
or it may be hydrogen.

The plumbing arrangement for this embryonic frog device is the same as for
a simple one like an Aerjec at a tenth the price. Fitting one forces the
plumbing to be corrected such that there is minimal pressure difference
between the vent pipe and the feed/expansion pipe. If that is done,
then the major reason for air entering is removed anyway.

===================================
I'm not defending or supporting the 'Tadpole' in any way, merely saying
that it should be tested properly. If it's found wanting then people
should be properly warned against wasting money, but if tests support the
claims made for it then it would be worth every penny of the cost.

Basically I'm sceptical as it appears to have nothing really new even if
the patent claim is true. One claim made for it is that it is 'small' but
compared with what exactly? A picture suggests that it is actually a large
drum-like item about the size of a small domestic bucket. In fact it
appears to be about 9" diameter and about the same in height. That would
give it a capacity of about 1.5 gallons (weighing about 15lbs / 7kg). I
certainly wouldn't like that kind of weight suspended in the pipework
adjacent to my CH boiler.

The claims made in respect of fuel savings will soon bring it to the
notice of Trading Standards, I'm sure. Similar miracle products for car
fuel savings soon come to a sticky end.

Picture here, hopefully:
