Every service card on this panel carries a handful of numbers beyond the price, and skipping past them is the single most common way to end up disappointed with an order that technically "worked."
Average start time is how long it typically takes for the first units to land after an order moves out of pending — this panel shows it as a real duration ("2 minutes", "1-3 hours") rather than a vague "fast" label, because that number comes from the provider's own reporting and varies a lot by platform and time of day. A service advertising an instant start that consistently takes hours is a sign the provider is overloaded, not that something is broken on your end.
Daily speed caps how many units can land per day even after delivery starts — a 50,000-follower order on a service capped at 5,000/day will take ten days minimum, no matter how urgent it feels. This matters most for larger orders: a cheaper service with a low daily cap can end up slower in practice than a slightly pricier one with a higher cap, even though the sticker price says otherwise.
Drop ratio is the percentage of delivered units that are expected to unfollow, get removed, or otherwise disappear over time — normal for engagement services since not every account behind a "follower" is a real, permanently active one. A 0-2% drop ratio is typical and unremarkable; anything advertised as "0% drop guaranteed" on a rock-bottom-priced service is a claim worth being skeptical of, since it usually just means the provider hasn't been tracking it rather than that it doesn't happen.
The refill window is the period during which the panel (via the provider) will replace any dropped units at no extra cost — 30 days is common, "lifetime" is a stronger guarantee some higher-quality services offer, and services with no refill listed have none, full stop. This is the number to check before buying if retention matters more than the initial bump, because a service with a great price but no refill leaves you fully exposed to whatever the drop ratio turns out to be.
Put together, the cheapest service on a category page is optimizing for one number — price — while start time, daily speed, drop ratio, and refill window are the ones that determine whether the order actually satisfies what you needed it for. Reading all four before ordering, especially on a service you haven't used before, is a two-minute habit that avoids most refund requests.
