Some further measurements I've done on my probe

x100 -1.12% (spec. +/- 2%)
Input referred offset:x10 + 9.8mV
x100 + 47.2mV
CMRR:Freq. x10 x100 Micsig Spec.
DC (50Hz) -89 -79 -80
20KHz -75 -74 -60
100KHz -72 -63 n.a.

Measured Bandwidth (-3dB):x10 128 MHz
x100 118 Mhz
Bandwidth Flatness: +/- 1dB +/- 3dB
x10 DC - 33MHz 33MHz - 100MHz
x100 DC - 33MHz 33MHz - 88MHz
Concluding:
Pros:- good overall performances considering the price
- very nice and compact package design
Cons:- CMRR below specification
- too long (and oversized) input cables can cause high frequency artifacts. I would have preferred them shorter (20-25cm) with a possible extension supplied (e.g. Tektronix approach...)
- BNC connector out of specification (it hardly enters the oscilloscope connectors, risking damaging them)
