Purchased these to ride Grinduro this past fall and have not taken them off my bike yet. They are great! I use my Salsa Warbird for touring, commuting, and mixed terrain racing usually swapping the tires for each specific style of riding but since mounting the Nanos all I've had to do to get the ride I want is change tire pressure. Also, not had a flat since going tubless.
Their one weakness is mud it cakes on and they cant find traction but they arent made for it so cant knock it for that.
Bought a pair of these last summer. Totally underwhelmed. If you live somewhere with soft, loamy soil or don't ride aggressively on pavement they'd be okay, but the lugs are tall and narrow and want to fold over in a hard turn making for a vague, uncertain feeling at speed on hard surfaces. The tread JUST BARELY covers the casing, so on a 25mm internal width rim the edges of the sidewalls are part of the contact patch and exposed to anything on the trail. I rode these tires for 2 weeks and then gave them away. I'd only buy this tire to ride loam in the midwestern U.S. with narrow road rims. This tire does not do well on anything but smooth hardpack.
