A quick review on the impact driver made by Ryobi.
This Japanese brand has a very nice set of good quality tools. It's well-assembled and it's heavy duty. The quality/price ratio is fair. The one-battery-for-all system is very handy and the Lithium 18v battery can be bought in different size which allows more or less autonomy.
This impact driver has a very sensitive speed control and 3 led lights to illuminated the target. The speed/pressure/torque are really easy to handle, when it's at its maximum torque you can barely feel it in your hand. It looks and feels heavy duty, the finishing touches show good quality. The tools is very well balanced and buttons can be handle with just one hand.
The change of screw tips is very simple and has a good, reliable release mechanism.
there's also a magnet at the front-bottom with a grip to hold and extra screw tip.
