Forgot to bump this thread long ago saw the cordless in my cupboard so bumping it again Price reduced to 5K final (really its a steal in this price)
Everything including chargers, base set, one cordless are 100% functional except one cordless ear piece and its battery as i am not using it else would have also got it replaced from market. I am sure that battery must be easily available and for the ear piece the defect must be minor as it arise just due to non usage of cordless
