Is the electric grill brush market on Amazon saturated?
Not oversupplied on listings - oversupplied on advertising cost.
The answer
63,434 monthly searches against 1,364 competing listings is a supply-demand ratio of 46.5, which looks workable. The problem is what a click costs.
At the $39.99 median on-shelf price the gross margin is 33.2%, but cost per click is $3.57. Advertising therefore needs a 29.9% conversion rate just to break even — roughly four times a realistic conversion rate for the category.
Two further constraints. The category swings 64x between peak and trough (111,309 in April against 1,733 in October), so inventory timing is a second bet. And the wire-bristle version of this product sits inside CPSC enforcement: a February 2026 statement describes bristles detaching and being swallowed unnoticed, with more than 3.2 million brushes recalled. Manual brushes are 72.7% of category units, so the powered segment is the smaller half.

Who this applies to
- You are buying inventory to resell
- Only above $70. At the $39.99 median price a $3.57 click needs a 29.9% conversion rate.
- You own the factory
- A powered brush without exposed wire bristles sidesteps the CPSC enforcement that covers the wire-bristle version - and manual brushes are 72.7% of category units.
- You are planning inventory timing
- Peak-to-trough is 64x (111,309 in April against 1,733 in October), so the buy-in date is a second bet on top of the price.
