"It's a $40 burr grinder, with all the compromises that price implies."
The '32 Grind Settings' provides a dial with 32 clicks, but the inexpensive mechanics mean the actual particle size output will be inconsistent and a poor representation of what those settings imply on a higher-quality machine.
This is a functional upgrade for someone currently using a blade grinder for drip or French press coffee. It introduces the concept of grind size adjustment for under $50, which is its primary and only virtue.
Anyone using specialty coffee beans or brewing methods sensitive to consistency (like pour-over or Aeropress) should save up. The inconsistent grind will waste the potential of good beans and frustrate any attempt at repeatable results.
