This cable is good for fairly slow speed signals. Starting at about 20khz it introduces a ring into the signal you are probing. About 0.75 volts peak to peak on a 0-5v square wave.
By 40mHz, this probe is worthless: An oscillator triangle wave (not sawtooth) looks more like a bad DAC sinewave on the oscilloscope.
Also, check the soldering at the hook ends. Mine had a cold solder joint on one hook that was causing some trouble with the signal.
A decent probe for the money, but it won't replace the normal oscilloscope probe.
