The 40-6625 comes ready to go, they even include the the 3 AA batteries to power the unit. It has a innovative soft sided pouch that can hold extra batteries and also includes a strap. There is an included mount that allows you to magnetically attach the unit to metallic surfaces, the mount is easily taken on and off via a dial that locks it into place, the tool and the included mount both have tripod mounts. Also included is a magnetic target which is great for a precise layout . The unit is rugged thanks to its over molded grip/cover. Johnson has a great 3 year warranty and they stand by their tools.

First thing when you take the level out of the package you notice that it feels quality. When the unit is in the off position it locks the pendulum protecting it from being smacked around. Turn the switch on and you are amazed at how bright it is. Johnson states that the level has a 150′ indoor range which we easily achieved in our tests. The level has an accuracy of 1/8″ at 35 feet and levels up fast. The lines are crisp and bright and you get around 20hrs of battery life. The laser has 2 modes auto and manual, in auto mode the unit self levels and a beep alerts you that the laser is not level. Manual mode allows you to use the laser at extreme angles, which comes in handy. There is also a slot on the side to calibrate the tool if you need to, we dropped the unit several times and it did not need to be re calibrated.
