Question
I found a product with 10k reviews on Amazon - does that mean it's too saturated?
Posted by •11/28/2025
Been doing product research for 2 weeks now and I keep running into the same problem.
Every time I find something that looks promising, I check Amazon and there's already products with thousands of reviews. The one I'm looking at now is a posture corrector - found a supplier at €8, could sell for €35, and there's clear demand.
But the top Amazon listings have 10k+ reviews. Some have 40k.
Does this mean I shouldn't bother? Or does high review count actually validate that there's a market?
I feel like I'm stuck in this loop where everything either has no demand (no reviews) or is "too competitive" (lots of reviews). There has to be a middle ground I'm missing.

Here's my actual process for evaluating "saturated" markets:
1. Read the 1-star and 2-star reviews (at least 30 of them)
2. Write down every complaint
3. Group them into themes
4. Find a supplier who solves the top 2-3 complaints
Did this for a yoga mat. Big brands had 20k reviews. But complaints were consistent: "too thin", "slips on hardwood", "smells like chemicals for weeks."
Found a thicker, non-slip, eco-friendly alternative. Costs more, sells for more, but the value prop is crystal clear.
Saturation is only a problem if you're selling the exact same thing. If you're selling a better solution to a known problem, competition actually helps you - they've already educated the market.

Ok this is actually helpful. I've been looking at review counts but never thought to actually READ the negative reviews as market research.
Just spent 20 mins on the posture corrector listings. Top complaints are:
- Digs into armpits
- Straps show through clothes
- Only works if you're already sitting straight (?)
The armpit thing comes up constantly. If I can find one that solves that, maybe that's my angle?

Now you're thinking like a real product researcher.
"Doesn't dig into armpits" is a MUCH better selling point than "posture corrector" because it's specific and addresses a real pain point (literally).
Next step: order 2-3 different ones from AliExpress that claim to solve this. Test them yourself. The one that actually works becomes your product.
One warning though - make sure this isn't a problem that's unsolvable by design. Some complaints are inherent to the product category. But armpit comfort seems like something that varies by design, so probably worth pursuing.

You're thinking about this backwards.
10k reviews doesn't mean "too saturated" - it means "proven demand at scale." That's actually what you WANT to see.
The question isn't "is there competition" - there's always competition. The question is "can I differentiate?"
For posture correctors specifically, look at the negative reviews on those 10k+ listings. What are people complaining about? Uncomfortable straps? Sizing issues? Cheap materials? That's your angle.
I sell in a category with 50k+ review competitors. My listing has 200 reviews. I still do €4k/month because I solved a specific problem they didn't.
No competition = no market. Lots of competition = validated market. Your job is to find the gap.
