Def recommend this. I pretty much use mine all the time on semis and trucks. 20" off road wheels filled 0 to full in like 2-3 minutes.

Just a personal note. I have used this for over year to bring with me on road trips. This is a much more robust unit that doesn't get hot after extended use. I was replacing the common small inflators that you can put in your glovebox. This inflator works well with M18 batteries. It may be capable of using a small M18 CP 2.0 battery but your really going to want to use a M18 5.0a or above. This is a great price. It is also what all the Tesla mobile service rovers use in the field.

Have used mine a few times the last few days with the insanely cold temperatures. Very handy to have and not have to mess with finding a compressor etc.

Nice to see all the love for this tool in here. I was disappointed I missed the Woot deal and found this randomly. I'm pretty deep into the Milwaukee ecosystem and I use the snot out of my M12 inflator and looking forward to the upgrade. Plan to leave the M12 in the car all the time, and have the M18 around the house/shop as it's much more convenient than dragging out the air hose from the big compressor.

I've never ordered from them before but I found a few reddit posts stating they were legit, plus they've been featured in several deals on SD before, and they're an authorized Milwaukee reseller so I went for it.

No doubt this is the finest inflator. (The m12 is also phenomenal) But is this deal indeed slick?

I did a quick check of my email and it turns out I have ordered from Way Source before without any issues. Coincidentally, my last order from Way Source was for the other model Milwaukee tire inflator.

Got 3 bats and the m12 stick pump. Don't see a deal on that super often.

This is one of my favorite Milwaukee tools, it is great when you need it in the winter due to how fast it fills the tires, really handy when the temperature suddenly drops and you need to to multiple tires on multiple vehicles.
