While mine is a prototype it's the same ergonomics just some minor differences. Mine doesn't have a folder, which for me i actually prefer.
Upside: solid jp quality in the entire thing, fully ambidextrous including action inlet, personally it might be the most comfortable chassis I've used, tons of mounting point options on the handrail.
Downsides: depending on what you want it is rather heavy (4.5lbs i think) though you may want the weight so that could be a pro, round tube jp forend while strong isn't always the best for bracing on the side of a something like a window or barricade fence post ect, accessories for the forend such as qd mounting is jp proprietary stuff so your options are limited vs something like mlock, cheek piece has no side to side adjustment (though for my face i found i didn't need it due to it being semi narrow in design so it doesn't push the face out much)
