Not a warranty !
And poster 1 is assuming mast was used to its design limits in first few uses.
Mast might not be put to its "test" for quite a while !(And still within design limits)
Why cant NP test all masts just post manufacturer (especially X9.)?
Perhaps they`d break too many !!!
Sounds to me as thoug NP are using customers as testers.
"It might break first time used but after that it should be OK "
Not confidance inspiring is it ??
