I did not invest in BIG. I had concerns about how many videos they could sell to small business and I had concerns about the fall in Gross margin. ISX's Gross margin showed a significant increase to 60% in the June half yearly.
See the post about BIG below from August 2017:
Gross margin was 33% in the first half, for the full year it is 25%. In my opinion, this is not a positive trend. A low gross margin will make it difficult for BIG to become profitable.
