Set your pressure and walk away!
This is an incredible little inflator, set the pressure and walk away. I use this for flat tires on customers vehicles that I can't reach with an air hose. Much easier than filling and carrying an air bubble to the car to fill the flat it is light and easy to use, however it is slow and unless you have multiple batteries one tire might be the limit, but used in accordance with its design it is a wonderful tool.

Not good
Have a lot of Milwaukee products and they have stood up to everything that I have thrown at them. This one, not so much. Worked maybe three times when my truck needed some air, now just makes noise.

I love this tool, but....
I use this for trailers, bikes, law mowers and tractors (almost everything with a wheel), it’s awesome, but after 1 year the pressure reading had gone crazy. I like enough I even bought them for my father and father in law...That said, I expect a lot longer life than 1 year. Can someone from Milwaukee help me with this problem?

Best Milwaukee tool I own
This little product is a powerhouse. It won't fill a tire as fast as a compressor but you can't beat the convenience and simplicity of this tool. For the price, this thing is awesome.

This inflator has Chutzpah! Just use ear plugs.
Overall, I think that this inflator is a good product. I purchased this as part of the Milwaukee M12 kit (miln2463-21rs) that inclused the Impact Wrench and a set of 3/8 metric socket set.
Just tried this out this morning to fill the tires in my wife's car. I like the digital readout that provides current pressure and then you can set the desired fill to pressure. Depressing the same "check pressure" button starts the compressor. As my title expresses, this unit is loud. I'm comparing this to my 12VDC corded VIAIR unit that is awesome by the way. You can barely tell the VIAIR unit is running most times. If you decide to buy this Milwaukee unit, just be prepared for it to be loud. Functionality is great. Just like most Milwaukee tools I own.

I am looking to buy at least two more!!!!
I didn't buy this inflator to air up my truck tires nor did I buy it to air up my car tires! I have bigger air compressor for that. I bought this M12 inflator to keep my lawn tractor tires at equal balance and also my airplane tires!!!! I love the simplicity of this Milwaukee tool!!! Screw hose onto tire valve stem, set your desired pressure and turn it on. It cuts off automatically when desired pressure is reached. It can't get no easier than that!!! I just live this little tool. It does exactly what it was built for!!! Thanks Milwaukee!!!!!

Good product overall
I have owned and used this product for about 6 months and even recommended it to others. I mostly use it on passenger tires and motorcycle tires. I have used it even to seat the bead on a motorcycle tire. My only complaint is that the inflator now reads about 11 psi before hooking it up to the tire. So i have to calculate this difference each time which isn't a big deal. There is a process to "re-zero" or re calibrate the inflator but this has not worked. I should send it back but honestly love having it in my truck.

I would not recommend this tool whatsoever.
I had an expectation that this compressor would work out for my needs. I was wrong. I have 12 and 18 V tools and the storage cart - which is just OK as the wheels do not work.... back to the compressor.

It has a hard time with any kind of trailer tire or truck tire - if I rode a bicycle I’d be - Golden.

I think if Milwaukee utilized their 18 V system they might have a great compressor — bottom line is the 12 V compressor is not good for any industrial type use — if you’re looking to fill bicycle tires you are all set. Milwaukee tools target market is not in the bicycle market which is confusing to me.... you should stay in your lane and market to the industrial folks that you have been. You might be coming out with a new mountain bike who knows !!

Not Happy
I'm a personal and own a lot of Milwaukee tools and most of them are M12/18. For the most part I've been satisfied. I purchased one of these going they'd work out and first it worked great, a little slow but the set it and go was good so I decided to get 2 more so each of our work trucks had one. One by one they've all stopped working. I'm hoping I can send them back but with 3 outta 3 failing I'm not sure I want them fixed and doubt I can get my money back. At this point I wouldn't recommend these.
