Airforce will fix my tank for free????

So iv had my condor for a while and it’s leaking at the top hat. I phoned them today to see the cost of getting it repaird but, to only be told that it’s covered under the warranty.

When I questioned about the warranty, such as when it would end, it’s a life time warranty?

WTF??
Not that I’m complaining but I didn’t think they did this.
Anyone else had the same experience?
