Isosiyete yacu roller shell ikozwe mubikoresho byiza kandi bitunganya ubushyuhe budasanzwe.Ubuso bwarwo burashobora kwambarwa kandi gukomera birasa, bihujwe nimpeta ya Happy Mold bipfa, ubuzima bwa serivisi buzaba burebure, hanyuma bigatuma umusaruro uba mwiza kandi woroshye.Ubu hariho kunyura mubwoko bwa groove, ubwoko bwa groove butambuka, impera ebyiri nubwoko bwimyobo nibindi ubwoko. Ingano nuburyo butandukanye byizunguruka birashobora gutegurwa ukurikije ibyo abakoresha bakeneye.
