Both units work well with a standard battery, but improve performance significantly when using a FlexVolt battery. Use a punch to install 2x4 torque screws to hold the TV mount. Did some light work. The drill is great. I highly recommend this set. This is a top set and therefore more expensive than others. You can find a better value with a lower rate. It works for me because I work hard on the exercises. In the future I will try to influence my overhangs on the tires and then let you know.
