Batani la COP SHANK High Pressure limaluma pang'ono DTH kubowola

Ubwino:

1. Moyo wautali wautumiki wa ma bits: Zida za aloyi, zokhala ndi moyo wautali wautumiki, zomwe zili bwino kuposa zofananira pamsika.
2. Kubowola bwino kwambiri: Mabatani obowola samva bwino, kotero kuti ma DTH amatha kukhala akuthwa nthawi zonse, motero amawongolera kwambiri kuthamanga kwa kubowola.
