Uhh correct me if I'm wrong but I'm pretty sure he's right and it's cheaper so why not?
Oh it has good features but when you look in the bag and really look into the specs it's just not the same. And cheaper? I guess so if you want a 5 year warranty as compared to a 7.
Other than all that yeah they're the same.
And then of course we now have a new champ in town. AX 850 which has all the features of the HX850 and is fully Modular ta boot.
