Cons

While the Kielder KWT-085-02 impact wrench has many great features, there are some downsides to consider:

• The price is on the higher end for cordless impact wrenches, especially if you need to purchase batteries separately. At around £250 for the kit, it's a significant investment.

• It's a noisy tool that produces up to 86 dB of sound. This level of noise can be fatiguing and potentially damaging over extended use without proper ear protection. The noise could be an issue in residential settings.

• The batteries take about 60 minutes to fully charge. While not terribly slow, some competitive models charge their batteries more quickly. The charger is also quite large and bulky.

• At 7.1 lbs with battery, it's on the heavy side for an 18V tool. The weight could become tiring if using it overhead or for extended periods.

• While the metal gear housing adds durability, it also adds weight and size. Some users may prefer a more compact plastic housing.

Overall, the Kielder impact wrench is a powerful, high-quality tool, but the price, noise, charging time, weight, and size may be drawbacks for some users to consider. Looking at comparable models may help assess if the pros outweigh the cons for your needs.

Comparable Models

The Kielder KWT-085-02 stands up well against similar 18V impact wrench models from other brands.

The Makita DTW285Z is a top competitor, with similar power and performance. It offers 1,740 Nm of max torque, just slightly less than the Kielder. The Makita has 3 speed settings while the Kielder has only 1, but they both deliver up to 3,200 RPM and 3,600 BPM for fast driving and loosening of bolts. The Makita is slightly lighter at 1.8kg vs 2.1kg for the Kielder. It comes with 2 batteries compared to the Kielder's 1 battery. Overall, the Makita provides comparable power and performance to the Kielder in a slightly more compact and portable package.

The DeWalt DCF899P2 is another close competitor. It has a max torque of 1,400 Nm, which is less than the Kielder's 1,790 Nm. However, it has a brushless motor and 3 speed settings like the Makita. It's the lightest of the bunch at only 1.6kg. The DeWalt comes with 2 batteries and overall is a slightly more compact and lightweight option compared to the Kielder, but it sacrifices some power.

So in summary, the Kielder holds its own against these major competitors by offering greater max torque and power while still providing brushless motor efficiency. The Makita and DeWalt options offer lighter and more portable designs with added features like multiple speed settings.
