First off all this is just a review how these things look like and how they feel when you use them, unfortunately I can’t test the limits of these probes since I don’t have the equipment to do so.
I ordered these 5 days ago and received them today, because the probes I got are not good anymore, while I was trying to calibrate the 10x compensation, the little screw of the adjustable capacitor went weird so it doesn’t change anything if I turn it (common problem on cheap capacitors).
I write this down because I was pretty impressed about the build quality of these cheap probes.
The probes are probably cheapest ones on Ebay, I ordered them from UK so they cost little bit more, but I didn’t want to get in trouble with customs here by ordering from China.This is the set I ordered from Ebay, it includes 2x 100MHz probes from UK seller

Probes feel really good in the hand and build quality is surprisingly good, specially compared to my 50MHz probe which cost me 15 times more long time ago.Specifications:

See below some comparing pictures with these cheap TP6000 probes, black 50MHz probes (don’t remember the brand) and Tektronix P6109 150MHz probes.
The package, I got 2 packs (4 probes)
The connectors, from above TP6000 probes, 50MHz probes and Tek P3109 probes:
10x compensation adjustment is on the connector and not on the probe itself:
The probes, TP6000 has a nice tip and good grip unlike the black 50MHz one. TP6000 is cheap but it doesn’t feel cheap when you have it in your hands, the black 50MHz feels and looks cheaper, I am not going to compare it with the Tek probe because its just unfair to compare 8USD probe to a probe which probably cost an arm and a leg to buy when they where new:
Ground lead, same order as before in above pictures, its slightly shorter than Tek lead, to be honest I like longer ground leads like the 50MHz ones even longer if possible, that just gives you more play room:
Tip compared to Tek tips, I don’t have the tip for 50MHz one anymore, but as you see the tip is exact copy of the Tek tips and they work quite same, it also fits on the Tek probes of course, so if you need a cheap hooking tip for your Tek probes these tips cost 8USD and you get free 100MHz probes as gift
I tested the probes (all 4 of them) on my 20MHz iwatsu ss-5702’s calibration output (0.3v 1kHz) just to see if they work, nothing further like testing with high or low frequency’s or different signal waves and voltages:
