Helpful information thanks. Mera butterfly steel coocker ka naya gasket lagaya to bhi safety hole se presure release ho raha hai, Would you please guide me what could be the cause
Both are good. Technically inner lid are much safer, Outerlid with reputed brands are good (Prestige, PREMIER , Butterfly, United etc), Steel (18/8, 304 grade) is best option. Recently triply Steel is in market. Go for it.
