Exhaust air is ported through an adjustable nozzle on the top of the gun

I was thrilled to find a viable powered alternative to the classic hand-powered staple gun! This stapler does a fine job of sinking Arrow T-50 staples into anything you want. You can staple away all day without a sore hand, and if you have reduced hand/arm strength, this tool opens up a variety of new possibilities. The gun itself is VERY small; even smaller than most 23-gauge pinners. It's so small and light weight that it almost feels like a toy, but it shoots staples into wood and engineered-wood products without any hesitation. No need to follow your stapler with a hammer to flush down protruding staples - as long as the nose of the stapler is flat on the workpiece, and you're getting appropriate pressure from your compressor, staples will be consistently flush. All in all, this is a HUGE improvement over your basic hand-powered staple gun, if you're anywhere near a compressor. HOWEVER - compared to other pneumatic staplers and small nailers, this tool is distinctly cheap. Not only in price, but also in quality. On par with, or slightly below, Harbor Freight standards for cheap pneumatic guns. In other words, functional, but not pretty or graceful. I suspect that it wouldn't stand up to heavy daily use. But for ~30 bucks, what do you expect? It works! At this price, buy an extra if you abuse your tools, and shoot staples two-handed until one gun breaks. The red plastic window cover (which is supposed to tell you how many staples are left) fell off the FIRST time I used this gun. Good thing that isn't critical - if anything, it's easier to see your remaining staples without that window cover in place. The rubber handle cover doesn't quite fit right, and feels like it would wear through and fall off with moderate use and scuffing. Paint is minorly chipped in a few places. In general, fit and finish are... rough. To sum up: If you're looking to upgrade from a handheld staple gun, this stapler will be a revelation. If you need to fire Arrow T-50-type staples quickly, easily, and consistently, this is your ONLY choice. However, if you're looking for a general-purpose pneumatic stapler, you can do better, even in this price range. (Hence the dropped star in my rating). A refurbished brand-name stapler (Hitachi, Bostitch, etc.), or a new mid-tier model (Husky/Campbell Hausfeld) will be a significant step up in quality for only a small step up in price. A few other observations about this stapler: -As has been mentioned in other reviews, don't buy special "fine-wire" staples - just go to your local hardware store or home center and buy the standard Arrow T-50 staples in whatever length you want (1/4" - 9/16"). I found them significantly cheaper at my orange home center than through this online retailer - I paid 10 bucks for a pack of 5000 Arrow-brand half-inch staples. -Staples are loaded from the bottom of the magazine, in contrast to most other guns I've used that load from the top or from the back. -Depth of drive is controlled by pressure alone; there's no adjustable drive depth on the gun itself. -The safety tip in the nose must be depressed against your workpiece before a staple is fired, and then single staples are fired each time the trigger is pulled. No rapid-fire "bump mode" that I could find. -It seems to use VERY little air - significantly less than my 18-gauge brad nailer (i.e. I can fire a lot more staples between compressor cycles than I can fire brad nails). -Exhaust air is ported through an adjustable nozzle on the top of the gun, as is typical for basic small pneumatic guns. -I think it's odd that the item description says "Narrow Crown" - I'd call this medium crown, especially compared to standard "narrow-crown" (1/4" crown width) 18-ga pneumatic staplers.
