Esikhathini esidlule, njengoba sazi ukuthi ukuze uthole isiphetho sangempela esikhanyayo, isinyathelo esingu-7amaphedi okupholisha idayimaneayikwazanga ukuphonselwa inselelo. Sabe sesiqala ukubona izinyathelo ezi-5. Ngezinye izikhathi babesebenza ngezinto ezilula. Kodwa kuma-granite amnyama, sizothola imiphumela emihle kodwa kusafanele sisebenzise i-buff pad. Ngakho-ke lapho isistimu yezinyathelo ezi-3 zokupholisha idayimane ivela emakethe, abaningi bethu bayangabaza: "iyini le gimmick? Izitebhisi ezi-3 zokupholisha ezivela e-Bontai zihlose ukuba isinyathelo esikhulu esibheke endaweni efiselekayo phezulu kwegquma lephedi lokupholisha, elingasiza ngempela ukunciphisa inani lezinyathelo ngokulandelana kokupholisha amatshe.

BontaiIzitebhisi ezi-3 zokupholishaatholakala ngosayizi 3″, 4″, 5″, ukujiya kungu-3mm, kuqukethe ukuminyana okuphezulu kwekhwalithi yekhwalithi yedayimane namakhompiyutha e-resin, kanye nezinye izinto ezintsha, ungakhathazeki ngokusha noma ukungcolisa endaweni yakho yetshe. Ukusetshenziswa okumanzi noma okomile kungenziwa ngesisekelo sesicelo sakho. Iguquguquka kakhulu, ikwazi ukuhlangana kahle, okusho ukuthi ayikho i-engeli efile ukuze ipholishwe. Sincoma isivinini esijikelezayo esingu-1000~4500rpm. Sisebenzisa i-nlon velcro yekhwalithi ephezulu ngemuva, yenza ukubamba isibambi siqine ngaphandle kokundizela kude ngaphansi kwesimo sokusebenza ngesivinini esiphezulu.

Lawa maphedi okupholisha azinyathelo ezi-3 agqama ukupholisha kwekhwalithi ephezulu nokucwebezela okujulile. Ukuze uthole lolo hlobo lomphumela, ikhwalithi kufanele ibe phezulu. Ukuhlola le sistimu yezinyathelo ezi-3 ezitolo zokwenziwa kufakazele ukubamangaza abakhi abangazange bakholwe ukupholisha okuhle okungaka okungafezwa nge-step pad engu-3. Nakuba iphedi isebenza kahle ohlotsheni oluthile lwetshe, esinye isici esibalulekile ukuthi Lolu hlelo lwezinyathelo ezi-3iphedi lokupholishainikeza imiphumela emihle ezintweni ezihlukahlukene, njengemabula, i-granite, itshe elakhiwe nezinye.

Lawa maphedi ngeke abe amaphedi anenani eliphansi kakhulu owatholayo, kodwa aqinisekile ukuthi azokongela imali eningi nezindleko kunezinye izinketho.
