Good when...
This is a great tool as I no longer have to drag a noisy compressor and tangle of hoses around to every job but jams way too often. Its very temperamental with the pins you use and has this warnings stuck to it on the magazine about this. I have found that Makita 23ga nails are the only ones that work in mine but even the slight variations in the nail pack can cause jams. The feed spring is too strong and often breaks the nail strips apart which then jam in the magazine. Its a good weight and fits nicely into slight spaces. Overall I like it, not love it. If Milwaukee ever release their 23ga version in the UK I'll buy that in a heartbeat!
