Ok, here is my quickie review of this Fiverr gig. I ordered 15k high retention views and here is what I got:
Order: 15k High retention views for $5
How Long: 6 days to fill (for only 15k views, it's too long)
Delivered Views: Just over 16k (hardly any overdelivery)
Retention: 95% on a 4 minute video
Source: Mobile views
Countries: Netherlands about 50%, US about 25%, Germany about 25%
Other Stats: I picked up 59 subs, not sure if it's from them or coincidence
Overall I would give these guys a solid B. Because of the weak overdelivery and mobile views (not nearly as good as FB referral for ranking), most of the reputable providers here in BHW are still a substantially better deal. Rock on Skittles, BigBuddy, Ruoall!
