My Mongdio grinder: espresso flowed fast even at setting 1

Reviewed: Mongdio Portable electric grinder (source model unspecified)Regional reference: Mongdio 38-setting portable electric coffee grinder (United States)

I switched from a hand grinder for convenience, but espresso still flowed quickly at setting 1. I described the result and the ensuing return dispute.

A hand holds a cream Mongdio portable electric coffee grinder with a round button and a transparent grounds jar. The source’s Chinese overlay repeats a warning to avoid it.

I used a hand grinder before…

With 18 g of coffee, I got about 36–40 ml…

I wanted something more convenient, so I bought an electric grinder…

Even at the finest setting, setting 1, the coffee still flowed very quickly, producing 75 ml…

I contacted customer service, and they said the problem was my coffee machine.

Update: Customer service kept asking me to pay the difference for a higher-tier grinder and wouldn’t accept a return. They kept insisting the problem was my machine rather than a shortcoming of their product. This was outrageous!

Interpreting the espresso result

The caption gives an 18 g dose and 36–40 ml output for the previous hand grinder, followed by 75 ml with the electric grinder. It does not state the electric dose, brew time, beans or basket, so the cause of the fast flow cannot be isolated from this account.

Later return follow-up

The May 27 caption reports that customer service blamed the owner’s coffee machine and proposed a paid upgrade instead of a return. In a separate May 30 reply, the author reported completing the return. The later comment records the owner’s eventual outcome; the original caption above preserves the earlier dispute.
