Ziphuphu zoseweretsa zimangokhala zovuta zotsekerera, monga omwe amapezeka mu ntchito zamagalimoto komanso kunyumba. Pamavuto akulu, makamaka ndi mnyumba zazikuluzikulu, pamafunika kuti mukhale osatetezeka kuti athe kupirira ziwembu zomwe zimapangitsa kuti pakhale pabedi kapena kutayikira. Pazogwiritsa ntchito kwambiri, zolimbitsa thupi, zolimbitsa zigawenga zamkaka, kapena mapangidwe ena amagwiritsidwa ntchito.

Ziweto zosewerera nthawi zambiri zimagwiritsidwa ntchito pazinthu zina kuposa zomwe amagwiritsa ntchito, ndipo nthawi zambiri zimagwiritsidwa ntchito ngati mtundu wokhazikika wa tepi yozungulira pomwe pali gulu lokhala lozungulira. Mtundu wa band screw umakhala wamphamvu kwambiri, ndipo umagwiritsidwa ntchito pazolinga zosasambiri kuposa mitundu ina. Ma Clajiswa amatha kupezeka kuti akuchita chilichonse kuyambira kukweza zizindikiro kuti azigwira limodzi mwadzidzidzi (kapena mwanjira ina).

Chingwe china chala ndi chiwopsezo cha kulemera chimatha kukhala china chomangika kapena "chidebe" kuti chipange ndalama yayitali, ngati muli ndi zochepa kuposa ntchitoyo amafunika.

Cons Clocks nthawi zambiri amagwiritsidwa ntchito muulimi. Amagwiritsidwa ntchito pa hoser a ammonia ndipo amapangidwa kuchokera ku chitsulo ndi chitsulo. Amoni ammonia a andmonia humu nthawi zambiri amakhala Cadmium yopangidwa kuti ateteze dzimbiri komanso kutukula.
