This is the semi-auto "assault gun" of screw guns. Nearly 2 years ago I saw a sale on Senco brand rechargeable screw guns. The price was right so I got one. As extra incentive it came with a "RotoZip" drywall tool that shares the two batteries and charger that came with the gun.
Each plastic belt holds 50 screws and they auto feed. I was helping with drywalling a sunporch a couple days ago and got to put it into action in a big way. With easy acces to where you want the screw you can shoot screws faster than 1 per second. In hard to access areas I could typically shoot a screw 1/2 way in or so and come back to it with a conventional cordless drill/driver. Screws come 1000 to a plastic pail. They are higher priced than boxed or bulk but I never stuck myself on a sharp tip or defective thread like I ALWAYS did with a drill/driver.
The guy I was helping was so impressed he just HAS to get one. He doesn't know but his wife already bought one as an aniversary present.
It shoots 3 lengths (one at a time as you have to select the length on a setting.) Depth of "dimple" is a simple knurled knob adjustment.
This thing is terrific for drywall but can be used for driving "drywall" screws into wood for other uses.
