Is a burr grinder better than a blade grinder?

Yes for most brewing. Burrs crush beans to a more even size, while blades chop unevenly. Even particles extract more predictably, which shows most in espresso and pour-over.

Can it grind fine enough for espresso?

It has settings down to the fine end, but budget burr grinders often struggle to stay consistent at espresso fineness. For drip, pour-over and French press it is on firmer ground.

What do the 28 settings cover?

The range runs from coarse for French press and cold brew to fine for espresso-style brewing, with mid settings for drip and pour-over. You adjust by moving the grind selector between numbered steps.

Does it work for single doses?

It is a hopper-style electric grinder, so it is built for holding a batch of beans rather than single dosing. Weigh your dose out and grind what you need.

How does it compare with premium burr grinders?

It offers a similar settings range for far less, but premium grinders add larger burrs, steadier motors and better parts support. Expect a bigger step up in consistency than in features.
