Precisely. And at the rate they are going they should be cash flow positive on that expense around, oh, 2020. We make a damn fine product if I do say so myself, but it's definitely going to be obsolete before then.

No, I really meant that if there are plastic end caps on the enclosure of a motor controller they will allow so much EMI to escape that there is no hope the controller will pass an EMC compliance test. The enclosure is essentially a tube, then, with both "open" ends acting as slot antennas.
