My Nanostriker XL showed up today! Overall it's very cool. I had to get Gunmetal because Orange was out of stock and well, I was too impatient to wait!
The ferro rod is smaller than most of my Firesteel.com models but it throws good sparks. The build of the XL is very impressive, and it works quite smoothly. I had a 10% coupon for Exotac so I bought an extra refill rod, another refill for my MatchCap XL and four more boxes of UCO matches while I was at it.
