Amazing Nail Gun
This nail gun gets the job done, hands down. The battery is powerful and it works better than any air nailer. I am so impressed with the power this gun has and the ease of changing the nail depth. This gun is worth every penny.

Excellent Quality - Compact Size
This Milwaukee M18 FUEL 18-Volt Lithium-Ion Brushless Cordless Gen II 15-Gauge Angled Finish Nailer Kit with 2.0Ah Battery and Charger represents an improved version of the 15 ga. finish nailer. It is a self-contained, battery-powered tool that is a very good choice for cabinets, finish work and trim functions. I like to use a 15 ga. finish nailer for thicker wood pieces where 18 ga. brads don’t seem strong enough. The full round heads hold better. This is a complete kit stock #2839-21CT and includes the nailer, a 2.0 AMP M18 battery, a battery charger and a nice embroidered emblem storage bag. All you need to get started is some 15 ga. 34 degree angled finish nails. I used Metabo/Hitachi 1 ½ inch nails in my testing and to reattach my trim on a new door. They worked great without any jams and each nail seated just below flush with small round holes. This tool offers two different easily selectable firing modes. One is sequential where only one nail is fired with a trigger pull and then two is where you hold the trigger down and the nailer fires a nail each time it contacts the surface to be nailed. There was no lag time between nails in my testing. I have two other pneumatic 15 ga. finish nailers and they work great but carrying around a compressor and the air hose is cumbersome and time consuming. It only takes a minute to get this Milwaukee finish nailer up and running. This is the FUEL version that utilizes a brushless motor and advanced electronics to deliver more power and make batteries last longer. This kit has a 2.0 amp M18 battery which supplied plenty of power for my needs and made the tool lighter. This nailer is heavier (7.5 lbs. with battery) than the pneumatic nailers but is more handy. I found that it was a little uncomfortable to use when working at shoulder level or overhead but waist level and lower was no problem. You can use larger M18 batteries but it adds weight. I like the 2.0 amp battery. This kit also includes the excellent M12/M18 rapid charger. It works great and charges very quickly. The manual covers depth adjustment, clearing jams and resetting the drive shaft if needed after clearing a jam. It’s all simple and I haven’t had a jam or any other problem. Just be sure to buy high-quality 15 ga. nails with 34 degree angle. This nailer has a 5 year warranty and the battery is 2 year warranty. Overall, this is an excellent tool. I have purchased several other Milwaukee M18 FUEL tools and every one has been great. I'm going to get the M18 FUEL 18 ga. brad nailer next!

Good nailer
This Milwaukee nailer comes with a battery and charger that charges the battery rather quickly for a quick turnaround. The nailer uses 15 gauge nails that are at every hardware store. You can adjust the depth of the nails and it is very easy to clear jabbed nail in the nail gun. Loading nails is very easy and quick and it comes with a nice carrying bag

Fantastic tool
I just love this nail gun. I have the first generation 15 gauge and I thought it was great. They have made several improvements on it. They redid the nose so it's smaller and more accurate to place the nail right where you want it. They have made it so it stands up on the battery. the belt hook has been moved to a better spot. The depth adjustment has stops on it. It has a different sound to it also. Highly recommend it

Excellent Complete Set
A cordless, Milwaukee nailer with everything included! How good can it get. The kit comes with the nailer gun, a 2.0Ah battery, charger, and tote bag. Everything you need to grab and go. Also makes it convenient to keep everything in one place. After charging the battery, all you need to do is load the slanted 15-gauge nails and tackle your next job. And the nail strips load as easy as you could ever ask for. Great for any professional or DIY. And next to the trigger, you have the buttons for Power On/Off, Battery Check, and Single or Multiple shooting. The 2.0Ah battery is sufficient to get you going, but I personally consider it a ‘starter’ battery for the tool. I stay busy with my nailers and commonly use a 4.0Ah or 6.0Ah battery for an average job. And of course, there’s plenty of room in the carry bag to load batteries, slanted nails, and any other tools you may need for your job, or helping a neighbor. Everything in one purchase

Compact and powerful
I am slowly converting from standard pneumatic tools to cordless battery operated and picked up this 15 gauge angled finish nailer. I needed to do some thick quarter round at the bottom of my carpeted stairs and needed longer nails with good holding power. This nail gun did the trick. It worked great for my use and was easy to get a nail in the tight corner by the wall and on the small wrap around piece. The angle helped some with that maneuverability and I wasn't sure at first if I would like that as I am used to a straight nailer. The depth gauge was easy to adjust and get dialed in to not over shoot and damage the fiber board moulding I put in while still getting the nail head set deep enough. I also like that this set came with a battery and the dual charger. I am disappointed in the bag because the nail gun doesn't fit very well. It has to be put in a certain way to easily close and that is annoying because at the end of a job I typically want to get my tools in quickly and be done. Overall I am very happy with the gun and its functioning, we will see on the battery life when I have to do a bigger job in the future, but the function and power are definitely there.
