I say laser make one hell of air hammer, bought it to do a number of automotive jobs, taking out ridiculously stubborn diesel injectors, pressing in and out ball joints and drive out a rear wheel bearing on a corsa c and took it all out no problem, it's one tool I use a lot of I had a cheap one but it isn't up to the job on serious stuff, what I like about the laser is it has variable air trigger and air flow adjustment knob so you don't apply to much hitting force which is important for drifting out injectors and other delicate jobs also you can tell it has a long barrel the blows are very strong on full power.
Very impressed with this hammer the fact it comes with a quick chuck rather than one of those dodgy springs tells you it's a quality tool.
