An LED light enhances visibility in tricky spots, and Type-C charging adds modern convenience. However, the low voltage and cordless battery limit its power and runtime compared to corded or higher-voltage tools. Durability is adequate for hobbyists but might not satisfy users needing a tool for more intense or frequent use. The tool is very easy to use, with simple speed controls accessible even for beginners.

This tool is a great match for DIY enthusiasts or hobbyists looking for a versatile, portable rotary tool for polishing and light crafting tasks but is less ideal for heavy-duty or professional applications.

The Milwaukee 2738-20 M18 18-Volt Fuel Lithium-Ion Brushless Cordless 7 inch Variable Speed Polisher stands out for its powerful performance, thanks to its brushless motor and battery-powered design. This allows it to offer corded-like performance, making it a great choice for demanding polishing tasks. The tool's speed is adjustable, which is crucial for different polishing requirements. Users seeking versatility will appreciate the variable speed feature, which helps cater to a range of applications from gentle polishing to more intense jobs.

In terms of ergonomics, the design appears to be user-friendly with a balanced weight distribution. The dimensions suggest it is relatively compact and should be easy to handle. The polisher is durable, a hallmark of Milwaukee tools, known for their high build quality and long-lasting materials.

Since the product is sold as a 'tool-only' option, users will need to purchase the battery and charger separately, which could be seen as a drawback. This might be less of an issue for those who already own compatible Milwaukee batteries. The absence of additional attachments or accessories in the package might also be a limitation for some users. Ease of use seems promising given its cordless nature, eliminating the hassle of dealing with power cords during operation. This polisher is ideal for professional users or DIY enthusiasts who need a reliable, high-performance tool for various polishing tasks.

This polisher is user-friendly with a variable speed trigger and dial, allowing for precise control during use. The ergonomics are well-considered, featuring a rubber gear case overmold to enhance grip and reduce surface imperfections. Users can choose to hold the tool via the front grip or side handle, offering flexibility and comfort during extended use. Durability is a strong point, with a sturdy build that should withstand regular use.

It is important to note that the product is sold as 'tool only,' meaning that the battery is not included and must be purchased separately. This could be a drawback for those who do not already own compatible DEWALT batteries. Additionally, at 4.8 pounds, the polisher is relatively lightweight, which can reduce fatigue during longer projects. This tool is particularly suitable for DIY enthusiasts or professionals who need a reliable, cordless polisher for various applications.
