To operate this gun, you hold the trigger down and get the drive up to speed (takes just a second), then drive screws by depressing the nosepiece against your material. The screws automatically advance along a track up the front of the gun. The trick is to not let up on the trigger after driving each screw, but to back off and press the nosepiece on the next spot while the drive continues spinning.

The gun features a reliable depth-of-drive adjustment that allows drywallers to get a correct depression every time without tearing the paper. We drove an entire clip in rapid succession and, using consistent pressure, achieved a uniform countersink every time. The depth-of-drive and screw-size adjustments are both toolless, as is the bit changing, which is done with a no-chuck, pop-in-type system. Changing screw strips takes only a few seconds, and the strips themselves are a nice size for conveniently carrying in a tool belt. All in all, the DuraSpin impressed us with how easy it is to use. It's lighter and more portable than competing collated screw guns, and strikes us as a must-have in a drywaller's tool kit. It isn't designed for use with an extension kit, however, so if you're going to lay floor sheathing, you'll need your kneepads.
