Amazon.com Product Description
Combining utility with traditional nailing power, the Hitachi NR90GR 3-1/2-Inch Gas-Powered Round-Head Framing Nailer eliminates the need for an air compressor by utilizing fuel rods and a rechargeable battery to drive standard round-head nails with precision. Ideal for general contractors, remodelers, construction workers, and service workers, the NR90GR will make short work of framing, sub flooring, fencing, sheathing, punch-out work, and more.

The NR90GR gas-powered nail delivery system is a powerful alternative to traditional pneumatic nailers. With no annoying hoses to wind, this nailer is capable of driving up to two nails per second and 1,000 nails per hour. A single battery charge will fire about 4,000 nails and a fuel rod will fire about 1,200 nails, which means you'll get the job done quicker.The NR90GR fires up to 3.5 x 0.131-inch round-head nails, whereas most of the competition falls off at 3-1/4 inches. This allows for maximum flexibility when working on various materials and applications. The adjustable depth-of-drive nose piece ensures each nail gets seated properly to suit the workpiece.
User-Friendly Design Reduces Downtime
With an easy two-step nail-loading procedure, the NR90GR will help you reduce downtime and improve efficiency. Simply slide the attached strip of nails into the magazine and release the feeder to lock the nails in place--you'll be ready to go within seconds. An E-Z view feature on the magazine prevents untimely reloads and keeps you on task.
For further ease of use, the NR90GR utilizes a six-nail lockout feature for preventing accidental dry firing of the nailer and ensuring proper loading and firing at all times. Additionally, the fuel rod door is double locked to eliminate accidental opening of the fuel-latch door during operation. A low-battery indicator gives you plenty of warning for your next recharge.
Designed for Comfort, Control, and Portability
Like all Hitachi tools, the NR90GR is ergonomically designed to enhance comfort and control on the job. To start, the nailer weighs just 7.9 pounds and features a well-balanced design that minimizes user fatigue and allows for easy one-handed operation. Additionally, the handle is wrapped in Elastomer compound to reduce vibration and prevent slippage for ultimate control. A collapsible rafter hook provides additional convenience by allowing you to hang the nailer from a rafter when both of your hands are needed.
The NR90GR doesn't require air hoses or a compressor, making it much more portable than a pneumatic nailer. Measuring just 14-1/4 x 4-1/4 x 13-29/35 inches (LxWxH), it will fit into tight spaces with ease.
The NR90GR Gas Powered Framing Nailer is backed by Hitachi's one-year warranty.

Better than the Pasload,Great nailer for what it is
This is a gun that is not as easy to use as an air driven one and does take some getting used to, I think that is where people have problems. Good balance and power and does not take the expensive, more limited Paslode round modified nails and will take up to a 3 1/2", 3 1/4" is not code in some areas and that is as long as the Paslode IMCT will shoot. I like not having to but anothe set od nailer for this gun as the Std. Senco style .
The fuel rod has to be in place correctly or the gun will not work correctly, sometimes you have to reinsert it if it does not seat the first time before closing the cover. There is a lock out on the nail strip to prevent dry fire so you need at least a 10 nail strip to start. You can not bump fire like so many like to do, wildly place nails all over, it is a sequential fire so you must place the nose on contact then let the fan start and fire,rated 2-3 nail/sec.. It takes some experience to learn how to use it. Go for an air driven nailer if you want to shoot it like a machine gun and have nails thru sheathing into air space like is the case in so many homes. I know bump fire can be done correctly but more often than not I see careless building results.
I have a Paslode finish nailer and it works fine, has its issues too, especially in having to be kept clean and use specific products for maintience as this gun has too.
The rubber grip on this tool and the balance is very good, hold the Paslode too you will see how much better this is. This is Made in Japan and not a cheaply made tool as so many tools are today. The fuel rod is from Germany, and does not have an expiration date like the Paslode fuel which will work too[Red rod]. They did have problems with the early Hitachi fuel but that is corrected now.
I do not like the depth adjuster and jam removal screws because you need a 5mm allen key that is supplied but does not have any onboard storage [it does have a spot in the nice case]. The depth adjuster should be tooless, I really dislike those 2 issues . There is also no rubber protector boot for siding or decking but again the Pasload boot will fit if you buy it. For the price it is a great tool IF you follow instructions and do not have expectations that it will act like an air framing nailer. I hope Hitachi will decide to make some finish nailers too.
Then there were two; Paslode has met their match.
I have always been a fan of the cordless nailers, I have two each of all of the Paslode guns. You can frame and finish a whole house w/ a gas framer, finish, and brad gun. I added the Hitachi Round Head to the mix just to have more flexibility in nails; if I run out and the closest supplier has one or the other styles I'll be covered both ways.
The comparison: I think the Hitachi has a better balance point in your hand. The Paslode is, I think, heavier in the nose, and so feels heavier. I like the Hitachi battery set-up better. If you get a piece of debris jammed in the Paslode along with the battery, it can be a bear to get out. The Hitachi is also easier to adjust depth of drive, although once you have it set, you rarely have to change it, unless you go from wood to microlams and back.
As far as the basic nailing, both guns perform the same. As other reviewers have noted, one down side to the gas nailers is that they require more pushing force to activate (so you can't use it as a gun like Danny Glover did in Lethal Weapon!). So if you have aligned two work pieces and are trying to nail them, you have a tendency to move the work when trying to activate the nailer. You also have to be careful not to leave the gun lying around with the battery in; it will run down.
The one performance issue on these guns is in extreme cold weather, especially if you are trying to nail over your head with the gun upside down. They won't fire. In those conditions, I kepp one gas canister in my pocket where it keeps warm, and I switch them when the one in the gun gets too cold. Note that in these conditions, you are also likely to have problems with your compressor, so the one is no worse than the other. Also, note that a pneumatic stick nailer probably holds 3-4x as many nails as either gas nailer, so you do have to lug around a lot of nails, and reload frequently.
All in all, I don't understand why I don't see these on every job site. Who wants to drag a hose through the truss webs if you don't have to. You can just hook this baby on your tool belt and climb around freely. And for the DIYer, I would highly recommend it. No compressor needed!
Works very well...just not for very long! 
When it works, this tool is a jewel; powerful, easy to handle, and it drives a true round-head nail. It's just that it doesn't work very long. The original unit acquired via Amazon lasted for somewhere in the neighborhood of a hundred nails, and then died. The local Hitachi dealer's service department could not revive it, so it was replaced with a new tool. The replacement lasted somewhat longer (200 hundred nails, perhaps) before it too ceased to fire.
The problem seems to be a flaw in the triggering mechanism that shows up after relatively moderate use. The dealer's service shop tried to repair the tool, and it worked for a dozen nails or so and then quit again. The dealer has been trying to get Hitachi to once again replace the gun, but the Hitachi rep. has apparently been unrepsponsive. In any event, unless the flaw is fixed at the factory, simply getting a new gun is no solution.
If my experience is anything to go by, purchasers of this Hitachi tool may be doubly cursed, first by a poor product design, and thereafter by poor customer service. My suggestion is to buy something else(which it looks like I'm going to have to do).
