Powertac?

Hey guys, I was wondering if any of you own Powertac?

I own 2 of the limited edition Warrior PK2 for collectible reasons.

I noticed the price of the Powetac Warrior Gen. 3 still holds value for some reason?

I am interested for some odd reason. The comparable ones I have are

Olight Warrior X, Klarus XT12, Nitecore TM03

Any feedback from owners of Powertac Warrior Gen 3?
