Short answer: Absorption, starting levels, dose relative to body size, and overall diet all vary from person to person — so the same product can produce meaningfully different results in two different people. The only way to know your own outcome is to measure it directly, not assume it matches someone else's experience.
Two coworkers start the same fish oil supplement on the same day. Three months later, one feels a noticeable difference; the other feels nothing at all. Neither is imagining it, and neither is doing anything "wrong."
Starting fatty acid status differs — someone beginning from a more skewed omega-6 to omega-3 ratio has more room to shift than someone closer to balance already. Absorption varies with digestion and individual metabolism. Diet composition varies — the same supplement dose has to work against very different amounts of background omega-6 intake from one person's diet to the next.
A product review or a friend's experience tells you what happened for them. It doesn't tell you what will happen for you. Reviews and testimonials are data points about someone else's starting point, not a prediction about yours.
A simple at-home test shows your personal omega-6 to omega-3 ratio before you start, and again after a defined period — commonly 120 days, timed to red blood cell turnover. That comparison is specific to you, not an average pulled from someone else's experience.

Does this mean the product itself is inconsistent?
Not necessarily — it usually reflects differences between individuals, not the product's quality.
Should I take a higher dose if I'm not seeing results others report?
Testing your own ratio is a better starting point than guessing at a higher dose.
How long before I'd notice a difference?
Meaningful shifts are generally assessed around 120 days, aligned with red blood cell turnover.
Can diet affect how well a supplement works for me?
Yes — background omega-6 intake affects how much a given omega-3 dose can shift your overall ratio.
