A lot of speculation saying they're junk with no actual experience with them.
Does that mean they wouldn't be effective?
Personally, I doubt I could ever get past the ad copy enough to actually evaluate the stuff.
They're at least mildly confused about what a logarithm is, they confuse units of measure (though "density mass" does remind me of a scene in
Back to the Future), they've taken it upon themselves to repeal a law of our physical universe which describes the behavior of fragments thrown off from a spinning body (if they were right about "rotational cones" we'd have no story of
David and Goliath as David would simply have pranged himself in the foot).
But it may have had something to do with the bad physics in
Wanted which at least gave us an episode of
Mythbusters for entertainment.
Let's say someone was trying to sell you a truck for 4 times what you were planning on spending but told you that, since the framistat was made out of a matrix of bombastium and bolonium it would bounce off toddlers and nuns in a collision but easily penetrate concrete bridge abutments and freight trains thus offering total safety to the occupants and innocent pedestrians while dealing death and destruction to anything that deserved it.
The bombastium / bolonium matrix also forces gravel thrown up by the tires to follow the tires rotation rather than flying off in a straight line thus minimizing damage to the paint and other vehicles.
You likely wouldn't buy it as, like most of us, you would feel insulted by the disconnect from reality / probable exaggeration. Alternatively, you might feel pity if the salesperson actually believed his spiel but not enough pity to pony up the extra money.
Either someone at ES
1. Hasn't read the ad copy or
2. Read it and believed it or
3. Read it and knew better but felt it was ok to lay on his potential customers.
None of these three alternatives fill me with desire to give the stuff a trial. If there's a fourth alternative, I'll be pleased to hear it.
Generally, any product invoking Majick Obscura, or its equivalent, to explain its performance gives me pause.
