Kubintu biremereye, akazi gakomeye cyangwa ibisabwa bidasanzwe kugirango ushireho ikimenyetso, wubatswe muburyo bwo guhuza ubwoko bwa kashe ya roller irashobora gukoreshwa.

Ibipimo byo hanze byikigereranyo birasa neza nubwa kashe idafunze, irashobora gusimbuza icyapa kidafunze inshuro nyinshi.

Impande zemewe guhuza ni 0.5 °, naho ubushyuhe bwakazi ni -20 ~ 110.Imyenda yuzuye yuzuyemo amavuta akwiye ya lithium yo kurwanya ingese, kandi amavuta nayo ashobora kongerwaho ukurikije ibyo abakoresha bakeneye.Ukurikije niba impeta y'imbere ifite imbavu n'akazu gakoreshwa, irashobora kugabanywamo ubwoko bubiri bwibanze: Ubwoko bwa C n'ubwoko bwa CA.Ibiranga ubwoko bwa C ni uko impeta y'imbere idafite imbavu kandi ikoreshwa rya plaque y'icyuma ikoreshwa.Ibiranga ubwoko bwubwoko bwa CA Hariho imbavu kumpande zombi zimpeta yimbere kandi cage ikozwe mumodoka.Ubu bwoko bwo gutwara burakwiriye cyane cyane gukora munsi yumutwaro uremereye cyangwa umutwaro uhindagurika.

Imyenda ya sikorike ifite ibyuma byerekana ingoma hagati yimpeta y'imbere hamwe n'inzira ebyiri n'impeta yo hanze ifite inzira nyabagendwa.
