No Leaks but fills slower then expected
You have to do the final assembly of the Schroeder valve chuck, and the Milton M type air hose fitting. They provide the teflon tape in the box.
I had zero leaks from the Schroeder valve chuck when clipped on a tire valve stem, the brass chuck appears to be of good quality. Same no leaks from the hose coupling fitting, when coupled with a Milton brand quick hose coupler.
I give this 4 stars as it restricts the air flow while filling a tire (much more then my old Milton air chuck). I filled the four .5 ton pickup tires from 25PSI to 35PSI, and it took about a minute per tire to increase the pressure 10PSI. When you depress the fill lever, the gauge reading goes to zero, so you have to release it to get a measurement.
I don't have any current means to check the accuracy of the pressure gauge. The .1PSI resolution is really overkill. But it does droop about .5PSI over a 20 second period, and the reading is repeatable when I unchuck and rechuck the Schroeder connector.
The gauge turns on automatically when it senses a pressure on the hose outlet.
The instructions don't say anything about completing the assembly with the hose fittings and teflon tape, which is what I assume the negative 1 star reviews were complaining about, as the fittings came finger tight from the factory.
Completing the assembly, the Milton type male air fitting used a 5/8 flat wrench which was very tight. The Schroeder chuck required a 14mm wrench. I used a bench vice to hold the hose and body of the inflator, so I can't reference a flat wrench for assembly.
The slow fill is probably real good for bike tires, and maybe the design intent, as it came with an European valve stem adapter.
I am happy with this, as I also have bike tires to maintain, and overfilling is very easy with the Milton S-506.
I'll update this review if I have any issues in the future.

Great value inflator/gage
Purchased for my home garage to monitor and inflate tires during routine maintenance. The package comes complete with two types of hose-to-tire valve fittings, 1/4 and 1/2 inch quick disconnect fittings, Teflon tape, four valve cover caps, and a valve core wrench.
The design, overall quality and materials are quite good.
In use, the gauge is easy to read, and the backlight makes it usable in dim lighting, but 20 seconds of illumination isn't enough time for the "normal" tire servicing. I'd prefer a longer timed illumination or an ON/OFF switch and a timed shutoff, and the contrast with the blue background and dark gray numbers isn't the strongest.
Being able to clamp the hose to the tire valve makes filling/adjusting tire pressure simple.
Filling the tire is done with the large lever, and pressure can be released by pressing the brass button on the side of the unit
The gauge is accurate when compared to a digital hand held gauge and with my car's TPMS sensor
Complete with everything needed to start inflating tires from a normal shop air source.
Good design, materials, ergonomics
Illuminated digital gauge
Four pressure system readings.
Clamp on tire valve
Short gauge light "ON" cycle time
The tire valve clamping mechanism must be oriented just right for accurate readings.

Great product and customer service
The digital tire inflator liquid display lighted and easy to read with very dark numbers. It is also easy to operate and the deflator bottom is comfortable to reach.
The only issue I found is that the air chuck does not seal properly on the tire valve stems. I only have metal valve stems on my cars, so I have to hold and press the chuck tight while using the inflator, but
AstroAl contacted me and sent me a replacement free of change. The new replacement works perfectly.

Easy to use and very accurate
Inflator works great for home use. I constantly checked the pressure of this unit against my other gauges during the first few uses and it's spot on. It's great not to have to hold the chuck on the tire stem when you're filling 70lbs in a tire. It only reads the correct pressure when you are not holding the handle down to inflate the tire. When filling and you want to check the pressure, just release the handle and wait about two seconds. The gauge and back light are auto turn on and off when filling or checking pressure.

air chuck leaks
like some, my air chuck does not seal correctly on the tire valve stems either. it leaks when I release the air chuck clamp.
the only way to make it work is to hold the press and hold the air chuck while pumping air. other than that it works good.
a replacement was quickly shipped and it work better. air still leak at the air chuck probably due to misalignment.
overall, customer service is great and and product is good.
I would buy again

it actualy works/seals well
reasonably accurate pressure reading, built well - most important the air chuck does not leak when filling the tire. comes with some freebies - the best the tire stem tool - you will need it someday. be sure to use the supplied Teflon tape to secure the air chuck and the nipple that goes to your air hose. reads in imperial, metric, and other scales, back-lit display
all in all way the Heck better than anything you can buy at NAPPA or other tire stores

overpriced for what it is
* does provide you with consistent reading but 1% accuracy - overstatement, shows difference of 10% with other trusted pressure monitoring.
* "upgraded" chuck is no better than standard - you would need to hunt for proper position on valve stem to got sealed connection.
* does not have mechanical on/off button. In couple months when you need to use it, the battery is going to be dead.
* the front part is thin flex plastic, not a glass.
* included manual does not specify parts in the set or how much tape to put on thread.
Overall it is functional, practical gadget just overpriced for what it is.
I'd rather pay more and get good mechanical manometer next time. Does anyone knows one for 60 psi max with easy to read 2" display?
update Apr 2018
I should admit, the seller is really serious on getting only good reviews on amazon. Good means 4-5 stars. No surprise they pump up average score so high (good :). He contacted me several times and offered replacement. So I did go for second one. The air leaking at inlet thread I have got on first one was simply because no one tells you how much tape to put on thread and force required on screwing inlet in. The seller rep simply ignored my request on that info and commented "just put tape next time". My problem was I put it too much in first place. The second time I put just 3 full turns of tape (follow direction of threads) and held inflater in my hand (no pliers) when tightened 1/4 inlet into the body. This combination gave me solid connection with no whispering air leak. The inlet went about 2/3 threaded part in and was really hard to tighten after that. See attached pics.
Don't get me wrong, as home use gadget it will last 3 years. All these years you are going to hunt for solid connections between "updated" chuck and valve stems and ... well keep adding new batteries too ;)
Let me help others not pro users who just need comfortable inflater. Do not put too much tape or force on screwing inlet. If you got air leak, stop, unscrew, remove all tape and start over. Yep, this is a part of the deal. No rocket since, you can do it!

on 2018-03-11 Comes with everything you need to fill your tires from a stationary air compressor
Although I recently bought an EPAuto 12V DC Portable Air Compressor Pump, Digital Tire Inflator by 100 PSI
to carry with me in the car, I prefer to use a stationary compressor to fill my car tires when at home. However, alternately using an air chuck and a tire gauge can be tedious, and my old air chuck didn't fit through the opening in the hub caps on my new Prius. This tire inflator is the perfect solution, and it even came with a fitting which plugs into my existing air hose.
To fit my air hose, I used the included 1/4" NPT quick-connect fitting (1/2" is also included), sealing it with the included Teflon tape. I also used the Teflon tape on the threads of the inflator chuck -- a very generous amount of tape is included. This comes with some other accessories which I haven't yet used: a screw-on chuck, a valve core remover/installer, and two extra valve cores. It also comes with four extra valve caps -- and I've already used one of those after losing a cap.
The chuck simply clips straight on to the valve stem with almost no loss of air, and the pressure reads out on the gauge. Just press the lever on the gauge until the pressure is correct. If you go slightly over, use the pressure release button on the back of the gauge stem to let some air out. When the pressure is right, release the valve stem and remove it quickly. With a little practice, it should be possible to limit air loss to no more than one or two tenths of a pound for car tires, but bicycle tires would be trickier due to the higher pressure and lower volume.
A very minor criticism is that the plastic face of the gauge did not have a protective covering and came with slight scratches.

Inaccurate description, inaccurate pressure reading, and valve leaks.
It leaks air through the hose. The valve doesn’t shut close. It also shows inaccurate pressure.
The “steel threaded” female fitting is not steel. Just plastic threads.

I stumbled across this gadget when I was shopping for an air compressor. I didn't know there was such a thing--as this add on to an air compressor. (I knew there was such a thing as an air compressor because there used to be one in my garage, but I gave it to my step-son after my husband had the temerity to die young, because what would I use that for? A few years down the road, I now know the answer: airing up tires and pneumatic tools! Doh!) If you have an air compressor this is a must-have add-on. It takes the guesswork out of inflating your tires. You just attach one end of it to the valve stem of the tire and the other to the compressor. It gives you the current tire pressure, if it's where you want it to be you're done. If you need to add air, this is the cool part. It's so exact. The first tire I checked was at 37.1 psi, I figured this was good. The next tire was at 36, I just pressed the lever for a second and Boom!, it's at 37 psii. (Maybe this is old technology, but this car/home maintenance stuff has been a steep learning curve for me.) My previous 'protocol', that one time I remembered- I checked the tire pressure at home, drove to a gas station and then filled and checked and filled and checked until it was right. Or more likely in my case, some kind soul in a parking lot told me I had a low tire. Oops. Drive to the air compressor hose at a gas station, check the air and add enough air so the tire doesn't look low anymore. Because the tire gauge checker thing isn't in the car, because I left it in the garage that one time I did remember to check the air. With this thing, my life will be a little easier. If I remember to use it.
