Today is my official one month anniversary with the service and I wanted to give an updated review and report.
I overall am very pleased with the service, I will most certainly continue it, and will most likely switch to the top tier when the new year rolls around and I get my promotion.
Pre-service I had ~35 followers and ~15-30 likes per picture.
Pictures are art, travel, and food. Every few pics is one of me in that place so people know I was actually there and not just taking them off google. Methodology is to post Thu, Fri, Sat, and Sun at optimal times I've found on each day.
I am working through my YUGE backlog of travel photos, pretending to be in one city till I run out of photos there, then 'going back home' for two weeks, then 'onto a new place', to further promote the idea that I'm constantly traveling around the world.
After exactly one month, I have 907 followers, my last 5 posts have 496, 825, 1245, 2368, and 1430 likes, respectively. My one issue, and this is addressed by Vinny above, is the inconsistency of the like boost. I have had to reach out to him and FlyHigher because sometimes it would take upwards of 20 hours for the boost to hit, but they were responsive and it ultimately worked.
Hope this helps provide a data point for those interested in getting into it. I am waiting to hit a couple thousand followers before actively using it to close in daygame, as most cute girls I open and find their IG have at least that many. To do so before I have more would be a DLV.
