Great battery nailer!
So far this nailer has functioned flawlessly. Easy to use, easy to adjust nail depth. Looking forward to my next project with it.

Solid, Reliable, and Surprisingly Easy to Use
I’ve been using the Ryobi R18GN18-0 Nailmaker for a few weeks now on a small home project, and I’m honestly impressed. It feels well-balanced in the hand — not too heavy, but sturdy enough that you know it’s built to last. The grip has a nice texture so it doesn’t slip even if you’ve been working for a while. Performance-wise, it delivers nails smoothly with no jams so far. I really like that it’s cordless (part of the ONE+ system) because it makes it super convenient to move around without dragging a cord or air hose. The trigger is responsive, and the depth adjustment is straightforward, which is great for switching between different types of wood. Noise level is reasonable — obviously not silent, but quieter than I expected for a nail gun. The battery life has been excellent; I was able to get through an entire afternoon of trim work on one charge using a 4.0Ah battery. If I had to nitpick, I’d say it’s not the lightest tool in the shed, so after a long stretch of work you do feel it in your arm. But for the convenience, build quality, and the fact that it’s part of the Ryobi ONE+ lineup (so I can swap batteries with my other tools), it’s totally worth it.

Nice Nailer
The product arrived two days earlier than expected, the product is new and works well. Thanks TheCountryButler, good job. Update april 02: Two days after purchasing it had a problem, it stuck a nail and it froze, the battery had to be removed and it did the same thing again, the solution was to use 3 in 1 oil to lubricate the tab that hits the nails, with that It is working 100% again. Update january 19, 2025: Despite having lubricated the tab of the machine, it would freeze on some occasions, the final solution I found was to add W40 inside of the machine in the tab, for example, you lift the lid to remove the stuck nails and at the end you can see a hole where the tab comes from, there at the bottom, I shot W40 and since then it has worked very well, I have assembled two pieces of furniture very quickly and easily, since I have it I have not put screws in small things or things that do not require much effort. Another important detail, you must keep the trigger pressed until the nail goes in completely, because if you remove it before the machine freezes and the light flashes. I hope this information is useful to you, because it caused me a lot of headaches not knowing this before.

Works better well
I am not a fan of some of the SAFETY features on this Nailer. If you hold down the safety tip onto your project, it will start blinking the light. It takes forever to reset so you can continue. I end up having to remove the battery to kill the cycle then reinsert it to carry on. For the price, this is a good crafting, Nailer. "Love my 18v Ryobi tools. P.S. Just make sure you buy "Ryobi original products. The Chinese compatibles are garbage.

As advertised-
I like it. As a DIYer, this is great. I have the compressor and air brad nailer but it takes a while to set it up. This is convenient and worth while.

If only it worked...
RYOBI does not honor warranties from this seller, West Brand Co - do not buy anything from them. Super disappointed. Worked great for about 20 brads and then stopped - flashing light, sounds like it wants to work (cycles) but doesn't shoot. Fully charged battery, fully loaded magazine with the right size brads, lubed, adjusted depth, etc. and yet nothing. Pulled the front off to find the striker stuck in the wrong position. Moved it back into the correct position. It shot one more brad and now doesn't even cycle - just nothing. Checked online for suggestions. Many posts are about the striker getting jammed, more lubrication, larger battery size needed and apparently it's quite temperamental and needs to be "warm" - I'm using it indoors during the summer months - does it need a heated blankie and a cuddle?! I think this one is going back - the intention of the purchase was to make my process easier, not add another headache. Yep, super disappointed, 'cause I love Ryobi tools.
