Cons

While the Kielder KWT-040-06 impact wrench offers many benefits, there are some potential drawbacks to consider:

• Price - At around £120, this impact wrench sits at the higher end of the price range. While the quality and performance seem to justify the cost, it may be out of reach for some buyers on a tight budget. There are cheaper alternatives available.

• Lack of accessories - The tool only comes as a bare unit without any included accessories like batteries or a charger. This adds to the overall cost since you'll need to purchase batteries and a charger separately if you don't already have compatible ones.

• Competition - Other major brands like DeWalt, Milwaukee, and Makita offer similar compact 18V impact wrenches that provide stiff competition. Some of these models may have more torque, better ergonomics, or additional features. However, the Kielder still holds its own with excellent power, compact size, and brushless motor.

So while this impact wrench has excellent specs and performance, the higher price tag, lack of included accessories, and competition from other major brands are factors to weigh when considering this purchase. It's still an impressive tool but may not be the best choice for every user.
