Before I bought one, I thought I'd never use it enough to justify the price. After I broke down and bought one, I wouldn't want to show up at work without one. Get a complete set of 3/8" impact sockets and universal sockets and you will be one happy technician. The trigger is fantastic and and it is light enough that my wrists don't get fatigued after using it for hours at a time. It's small enough to fit between the radiator and engine when I'm pulling water pumps off 5.7L Tundra's, just as a specific example, and is truly a time saver! Strong enough for most bolts I've come across up to 21mm, anything bigger I go grab the half inch. You won't regret it!
