Overview
At $8.99 for three double-ended open-end wrenches, the HARFINGTON set covers six SAE sizes: 3/8 and 7/16 inch on the first wrench, 1/2 and 9/16 inch on the second, and 5/8 and 11/16 inch on the third. This compact bundle weighs just 0.15 kilograms total and measures 165 millimeters in length, making it easy to slip into a compact toolbox or glove compartment.
With 200 units purchased monthly on only 55 reviews, this is one of the higher purchase-to-review ratios in the batch, indicating buyers often skip leaving a review because the product simply works as expected. The 4.7-star rating across those 55 reviews reinforces that the tools meet expectations consistently.
For home mechanics and apartment dwellers who need a handful of common SAE open-end sizes without spending on a full 20-piece set, the HARFINGTON three-wrench bundle is a sensible, low-risk addition. The $8.99 price is lower than most single-wrench purchases from premium brands.

Performance notes
The HARFINGTON three-wrench set measures 165 millimeters (approximately 6.5 inches) in length and weighs 0.15 kilograms (approximately 5.3 ounces) for all three wrenches combined. The size range, 3/8 through 11/16 inch, covers fasteners commonly encountered in light automotive work, small engine maintenance, and general household repairs. The low combined weight suggests a relatively compact profile that fits in tight spaces. No material spec is published.
What buyers say
Owners report that the jaw sizing is accurate and that the wrenches hold up well for light to medium use. Given the high purchase volume relative to the review count, it appears many buyers use them and move on without complaint. The 4.7-star consensus among those who did review confirms the product delivers on its basic promise.
