"Both the ESC and the box came very well protected and package with foam, unlike the most of the other ESCs that are on the market that comes in either ziplock bag or a tiny box without any protective wrap.
Size Wise, this ESC is quite a bit larger than the jive 120+ and the CC85HV that is ever so popular. The Mega Power 120A HV has a larger footprint, thicker body and is heavier than the other two ESC. A fairer comparsion might be the Mega Power vs CC110HV, but unless someone is going to buy me a CC110hv or the coming ICE125HV, I am not going to get a ESC just to take photo. Nonetheless, it is still way smaller than the Turnigy or Hobbywing ESC that are really big. Build quality wise, I really have got nothing to complain about because everything is enclosed in the box and even the capacitors are "embedded" in the casing. The cooling fan is probably a god-sent feature that will be great for our local climate, especially if you are mounting the ESC within the canopy.
The cooling fins look big and rugged and the wires are of appropriate guage size. Nothing to complain here either. On my first few power up, there was NO Spark from the higher voltage lipo and I realise that this has actually got a SPARK ARRESTOR BUILT IN."
