I've seen some pics of the coaches in like a setting on the voice stage. They must have now filmed battles. I'm not sure how many episodes of blinds are remaining. I believe it will be better since the coaches have now got a little experience and have familiarised with the show.
The later blinds episodes have been good in terms of their pitch.
I feel sad for Coach Jaydee, she's only popular in Kenya and Tanzania and isn't a choice for many contestants. She'll have more 1 chair turns than any other coach. I hope she coaches them well and do good
