I have a paragon and have a manhattan on order. They are very different mods ( as different as mech mods can be that is)
I love my paragon. I carry it daily, love that it starts up conversations at all vape shops or meets i attend. Its different and thats cool. It hits like a champ, and is easy to keep clean. Im just a sucker for carbon fiber too.
Now hat being said.. The build quality is not as nice as I would like. My lock ring gets stuck often and its a pain to get free without scarring the copper. The pin and insulator fall out every single time I change my battery and this seems to be a common thing among other paragon owners ive talked to. The threads also occasionally get stuck on the top and lower sections making it difficult to remove sometimes.
I love this
mod, but its kinda like being in love with a drunk crazy chick. Shes wild, lots of fun, performs great when she wants to but is also a high maintenance pain in the .... who will at times leave you frustrated as hell.
As far as the manhattan.. I have used one and liked it very much. The switch is smooth as silk and it hits like a hammer as well. The finish was quality, and the threads seemed to be on point. I have not had extended time with it so I cannot really comment too much on it but I liked it enough to order one.
hope this helped!
