108 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Cordless F3 runs on an 18-volt battery platform and produces a no-load speed of 8000 RPM. That speed is on the lower end for cordless angle grinders in its price class, which affects its ability to handle harder materials or tasks requiring a faster wheel surface speed.
At 1.63 kilograms, the F3 is reasonably lightweight for an 18-volt cordless grinder. The weight advantage may benefit users doing extended overhead work. However, the 3.9-star rating from 108 reviewers is the lowest rating among grinders in this batch, sitting just above the 3.8-star quality floor, which is a signal that buyer experience has been inconsistent.
With 100 units sold last month at $49.99, the F3 sees moderate demand. Buyers comparing the Cordless F3 against the RYOBI PCL445B (also 18V, $58.95, 4.5 stars, 9000 RPM) or the SEESII AN01 (21V, $49.99, 4.3 stars, 19000 RPM) will find those alternatives offer more documented satisfaction at similar or nearby price points.

Frequently asked questions
Is 8000 RPM enough for an angle grinder?
8000 RPM is on the lower end for angle grinders. Most standard grinding and cutting discs work adequately at this speed for light tasks, but faster options in the 9000 to 19000 RPM range handle a wider variety of materials and are more common at this price.
How does the Cordless F3 compare to the RYOBI PCL445B?
The RYOBI PCL445B runs at 9000 RPM and holds a 4.5-star rating from 257 reviews at $58.95. For most buyers, the RYOBI offers better documented performance for a modest price difference.
