The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The Milwaukee 2888-20 carries two standout figures: a 4.9-star rating and a 1-pound body weight. Within this batch it is the lightest grinder listed regardless of power source, and the 4.9-star average is the highest. Both figures are meaningful, though the 79-review count means the rating is based on a smaller pool than the 2,400-review Milwaukee 2880-20.
Running at 8500 RPM on the 18-volt battery platform, the 2888-20 shares its RPM spec with the other Milwaukee 18V models in this batch. What sets it apart is the 1-pound weight, which is dramatically lower than the 2880-20 at 79.82 ounces and even lighter than the 2886-20 at 19.19 ounces. For tasks where arm fatigue, reach or single-hand control are the main concerns, the weight differential is substantial.
At $161.98 the 2888-20 fits between other Milwaukee options in price. With 200 units sold last month despite only 79 reviews, it shows active market demand from buyers who likely already trust the M18 platform. The 4.9-star rating, if it holds as the review base grows, would make this the top-rated grinder in the category.

Performance notes
At 8500 RPM on an 18-volt battery, the Milwaukee 2888-20 handles the same grinding, cutting and prep tasks as other M18 grinders. The defining spec is its 1-pound weight, enabling overhead, single-hand and fatigue-sensitive work with minimal strain. No wattage figure is published; performance in heavy-load applications should be confirmed from owner feedback or Milwaukee's spec sheet.
What buyers say
The 79 reviews at 4.9 stars reflect a highly satisfied early owner base who predominantly cite the extreme light weight as the defining reason for purchase. Feedback consistently praises how little the tool weighs for an 18V cordless grinder. No significant negative patterns appear in the current review volume.

Frequently asked questions
Is the 4.9-star rating on the Milwaukee 2888-20 reliable with only 79 reviews?
