4 pieces I have stuck to the bottom of my small radios (TDV-26)
that accompanies me every day on the job, the magnets hold it securely and firmly,
even whom I have once the workshop trolley across the courtyard, courtyard is with us
paved and has already put some rupige, the radio stays in place.
In addition, I have some magnets (3 pieces) mounted on an old gooseneck,
and thus have already desöfteren small screws from the bottom corners get,
He has held and pulled out easily even a 17er Ring mouth.
By contrast, these magnets are the construction market are in these telescopic stems of pure joke.
My conclusion:
Super magnetic force - Good price - Felt 1000 Application possibilities
