Really good and nice load for the money.. they are really cheap, so i did not expect much, but it does solve the task, specially if you are on a budget.
A bit unstable especially at higher input voltages :
10nF C58 removed, now acceptable (but not perfectly silent)
Solderings a bit fast made, missing cleaning, solder drops a few places,
Banana plugs too large hole, but who uses banana connectors for high currents anyways, a bit funny menu / setup system, but with a little bit practice it actually goes ok, specially when looking in manual at the same time, a few funny errors in manual found, ha ha it is NOT nixie tubes :-) like they say. Manual say a KP184 weight is 4.5kg but it is 3.4kg !!
it is a bit susperious they also say the KP182 (the 200W type) weight is 3.5kg
FETS used 6 x IRFP250M they handle 250V
Calibration manual found here :

I use auto generated subs, I go thru them my self, but i am far from perfect at finding all errors, so if you find errors worth fixing, please comment (or PM) with the TIME in the video you saw the error, i will be happy to fix it. This also apply to the Danish version.
