The battery is easily inserted and installed. I would have preferred flexible silicone wire and a little longer, but it still works great. I just didn't like the price and the thought of soldering and building a block and this device allowed me to connect two wires and the machine works great with all my Dewalt batteries of which I have plenty and also allows one quick and easy charging swapping blocks i could you can't do without buying additional expensive packs for the car. This is a great solution, and as a bonus, the yellow color is very close to the color of the car.
