Looks like OP's business has been slow for last month. So here's my review:
Recommended? Yes, Must Buy.
Investment? Yes, but not necessary. The most expensive investment you'll do on this e-book is buying Alidropship. (you can do this for free with Shopify partner program)
I highly recommend this e-book for people who want to cash-in on the new & best traffic source of dropshipping (Instagram).
Pros:
The e-book contains OP's experience in using Instagram. It has everything such as a case study on creating a Instagram Business account, OP's own recommended settings, OP's own niche, (Heck) even finding new niches, and more.
Cons:
None.
No false promises.
Final word:
Stop wasting your money going blindfolded. I ensure you that you'll make a lot of mistakes. I compared this e-book with BHW's free methods and most of them are considered as "mistakes" in the e-book. The e-book explains why and contains much better alternatives.
I'll provide payment proof by making my own Journey soon.
