bought it a few days ago and i have to say its good to the hand. the feel is fine and it doesnt seem to discolour or lose its texture. pretty good materials as far as i can tell and very very hot! however i believe there is a temp sensor that measures outside temperature so sometimes when im inside it seems more warm than when i use it outside. perhaps its the temp difference but all in all very good . i dont know about the battery life but i dont really care since i will use it max 4-5 hours and only in the winter. seems a little big to the hand ( i have small hands ) but its comfortable enough to hold in your pockets.only thing that is a little irritating is its not charging with every cable. perhaps its my charger or the cable itself but i dont think that would be an issue since im using an ipad cable thats notorious for charging things apart from ipads. so yeah pretty solid and a nice to have.
