Our Verdict

While the Mueller HyperGrind Precision is quieter than many competing blade grinders on the market, it didn't particularly impress us in any of our other tests. Like all blade models it grinds quite inconsistently, it tends to make a bit of a mess while you're using it, and the permanently affixed grind cup makes it nearly impossible to clean the machine thoroughly. Even if you're willing to sacrifice grind consistency in order to pay less for a blade grinder, we wouldn't recommend the Mueller HyperGrind Precision.

Pros Inexpensive, relatively quiet for a blade modelGreat grind consistency, intuitive interface, relatively clean and quietGood grind consistency, burly componentsQuiet operation, good grind consistency, great for pouroverAbove average grind consistency, clean operation
Cons Inconsistent grinds, messy, hard to cleanNot ideal for French press, expensiveExpensiveCan produce enough static to hang onto grinds, not great at the extreme ends of the grind spectrum (coarse and fine)Slightly pricier than some comparable models
Bottom Line All the disadvantages of a blade model without many redeeming qualitiesTop-notch performance in every category except for French pressA consumer-level model that is built more like a durable, commercial-level machineGood grind consistency from a relatively quiet machineUnlikely to win any popularity awards, but just as unlikely to displease

Our Analysis and Test Results

While the Mueller HyperGrind Precision generally functions like most other blade grinders on the market, some extra annoyances with its cleanliness and ease of use dropped it to the bottom of our scoresheets.

Performance Comparison



Likes


The most pleasing thing (or, more accurately, the least displeasing) thing about the HyperGrind Precision is the noise that it emits. One generally expects a blade grinder to sound a bit like a plane propellor crashing through a jungle canopy, but the HyperGrind manages to keep its noise relatively innocuous and at a fairly low-medium pitch. Still, it does create quite a cacophony for a few seconds before the beans break down a bit.

The HyperGrind often spills grinds when you remove the cap.

Apart from not sounding as grating as some other blade models, our only accolade for the HyperGrind is its price. It is a lot cheaper than all of the burr models we tested, and is on the lower end of the price spectrum when it comes to blade grinders as well.

Dislikes


Unfortunately, our list of dislikes for this machine is longer than our list of likes.

First off, like all of the blade grinders on the market, the HyperGrind fails to create a consistent grind size. This is because its blades are pretty much randomly slicing through a pile of beans with no way to control the actual size of the particles it produces. This results in a different amount of large and small grinds everytime you make coffee, and is likely going to result in a different taste and sub-optimal extraction everytime. This is just the big sacrifice you make with a blade grinder, with the only other option being spending likely orders of magnitude more on a burr grinder.

A good amount of coffee gunk sticks to the hard to clean grinding chamber.

Our biggest gripe with the HyperGrindis the mess that it makes when you use it. This comes from the large amount of fine coffee dust that is produced, which sticks all over the grind cup and generally must be cleaned off with a brush or rag. That stuck coffee also makes pouring the grinds into your coffee maker less than predictable, as sometimes the grinds pour slowly and smoothly and sometimes you get a sudden coffee avalanche. This resulted in us dumping a good amount of grinds onto the counter while using this machine.

This problem with small grinds that gunk up the machine is made worse by the fact that the cup with the actual blades in it cannot be removed from the machine. This makes it nearly impossible to get the blades fully clean, as you can't run them under a faucet or put them in the dishwasher.

Value


The Mueller HyperGrind Precision is quite inexpensive. However, we've found similarly inexpensive blade grinders that we've liked slightly better. In general we've found the differences between blade grinders to be small, but if we're splitting hairs we would say there are better values to be found in other blade grinders.

Conclusion


The Mueller HyperGrind Precision was one of our least favorite grinders, but it also sells for a rock-bottom price.
