Which follower service should I pick?
Each service lists its quality, start time, daily speed and refill in its name and description. Basic-quality followers are the cheapest way to lift a new profile's count. High-quality and non-drop services cost more but hold up better over time.
If you are growing a brand or a shop, a service with a refill period is the safer choice: if some followers drop within that period, you can ask for a refill from your order log.
