im using rx200 now...no problem with mine...i guess the latest firmware had fixed all the issue...
however,the only problem i had is,the 3rd battery slot that nearest to the back cover 1,when want to remove if not careful enough it will cause brown big spark. its also my battery cover is loosen just alittle bit.
wont be a problem if i just carefully push the battery backward and remove it or just remove the negative side 1st...
some other cons are...1st batch back cover loosen you can see some gap,not a big deal. while the latest batch (red black version) they fixed the gap however it become too tight now,very hard to remove back cover,what i did just stretch outward gently the positive from negative battery slot,problem solved...
at 1st it feel very heavy but after used to it it just feel alright

not gonna lie,its gonna feel awkward fitting into your pocket,but im carry a bag so that's not gonna be a issue for me

Haha I think I will go see the real product first see if it fit nice in my pocket and not look like a penxs xD
