my last finger's skin started to peel off... how did u guys hold it? finger feels damn painful

bro daijoubu, my powerball vibrates quite obvious and quite noisy.. is it faulty or need cleaning? i only gotten it for 2 days

bro daijobu, i had a problem with my powerball & they asked me to send back the rotor to them for replacement, from your experience, how much would the shipping cost? is it worth sending it back or should i insist on getting it replaced and not sending back? its troublesome to send back to them
