Also interesting is that I believe the MTE was available before the NCDI...
Supposedly, the design of the NCDI was stolen during production, and MTE copied it, trying to beat them to market. The 20-mode versions were the first seen.
When you say NDI which manufacturer are you referring to ? The link above looks alot like the MTEC3 - 70101, but does Deerelight manufacture a light similar to this.
NDI = NiteCore Defender Infinity
