nice machine but machine cost, electricity cost also need repair and maintenance cost so its not reliable for large community
if 50 muslims use this machine daily then its usage is 250 time per day it will need repair per week and it is electronic machine so it also need electronic parts
large masjid can't handle this thing if small masjid need check up in week then in big masjid its need daily repair and daily check up so costly then weekly check up
ap ECONOMICS ka subject zaroor parhain Govt kabi aisi cheez instal ni krti jis ki check up daily base ho r check up cost machine ki cost sy upor nikal jay
