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 2886-20 stands out for its combination of high rating and extreme light weight. At 19.19 ounces, it is dramatically lighter than the Milwaukee 2880-20 in the same batch, which weighs 79.82 ounces. Both run at 8500 RPM on the 18V platform, making weight the primary differentiator between them.
The 4.8-star average from 330 reviews reflects strong user satisfaction at the premium $199.95 price point. With 200 units sold last month, the 2886-20 demonstrates steady demand from buyers who specifically seek the lighter form factor. No motor wattage figure is published, so direct power comparison with watt-rated models relies on owner-reported performance.
For contractors doing extended overhead grinding, tiling or metalwork where sustained arm fatigue is a concern, the weight difference from heavier 18V alternatives is a meaningful advantage. That advantage comes at a cost premium over similar-platform options.
