Used once, for what I'm doing (a small car, 32 PSI) is really good. Easy to use as well.

Impressive, 21 psi to 29 psi in under 30 seconds but it took longer if you need more then 30 psi. Going from 20 to 31 took almost 2 minutes.

My husband initially gave me a hard time for spending this much money on a tire pressure gauge but when we used it for the first time today, he (and I) both were delighted with it. It was so much easier to attach it to the valve on our motorcycle and scooter, we liked how easy it was to see the current pressure without disengaging the tool. We liked how easy it was to let air out until desired pressure was achieved... again without disengaging the tool. Awesome! I'm happy I bought it!

Works really well! Make sure that you buy the right PSI for the cartridges. There isn't enough room for a PSI gauge (and that would make it a lot more expensive) but if you have the right cartridges, it works like a charm. I had a slow flat I couldn't fix the other day, and so I was able to use it twice to limp my bike home by using the shutoff valve. So much easier and more enjoyable than using a tiny pump!

I like this pump.  Easy to use and the large pressure gauge is a big plus since I don't wear my reading glasses when I pump up my tires.

I bought this because of its independent fuse (I've heard of people blowing fuses and remaining stranded without this) and its compact size.  After buying it, a neighbor told me he bought something similar without the independent fuse for about a quarter of what I paid.  However, when needed in practice, this delivered - rapidly adding air to a partially deflated car tire.  The compressor is well made and the connectors are very solid.  All in, very impressive.

From what I've heard, the cheaper alternative took about 6 times longer to fill the same amount of air, had attachment problems and felt cheaply made.

This inflator is very easy to use. I pumped up all four tires on my car, only one had pressure three were below 12 PSI and it took less than 25 minutes. I checked the inflation rate, it was 3.5 PSI/minute. Not fast, but not bad. The digital pressu8re gage made inflating the tires a snap.
Best inflator I've used in the last ten years.

I've only had it a day, but used it quite a bit and I really like it.  I can't believe how quiet it is.

It arrived without damage, packed very well.

Assembly was quick and easy.

I used it with an impact wrench and to air up tires.  When tank pressure dropped enough to kick the compressor on, it kept my tools running and gained pressure in the tank at the same time.  My old compressor simply can't compare to this one; it's excellent!

I'm really happy with this pump. The gauge is accurate, the pump moves a lot of air, and the nozzle works well with both Presta and Schrader valves. I'd recommend this to anyone who needs a pump.

I bought this to check the PSI on my tires every now and then. It works pretty well. I feared that it would leak air due to a bad seal as mentioned in other reviews, but this seal looks legit. It uses a CR2032 battery that you can change if it goes bad (but it shouldn't for a long time). It does keep the PSI readout on the screen for a few seconds, just in case you have to raise it up to view it better. The only thing I would suggest for this gauge is a little pin or something that I could use to let some excess air out. Other then that, its a pretty handy gauge.

I just got a low tire pressure warning pop up.  The tire was only at 25Psi and recommended is 33Psi.  Retrieve this little pump from the compartment and run it.  It took less than 1 min to bring the pressure from 25 to 33Psi. Very happy.

I have all four tires inflated and it didn't overheat (perhaps the outdoor temperature is only 35F).

Very nice tool when you need it.  And easy to store didn't eat up too much space.

Really good .... a very effective, yet inexpensive pressure washer ($75). It lacks some extra features (e.g., like a quick release valve for the water hose), but overall I am very happy with its lighter weight, overall performance and smaller foot print. The lower 1450 PSI has already proven itself more than enough pressure to easily clean house siding, wood fencing and garage doors, concrete sidewalks, stucco and other areas. This pressure washer will make prepping our house much easier for a new painting (which is the reason for our purchase after an older pressure washer finally broke after 15 years). Assembly was easy.

This pump is easy to use and attaches securely to the valve.  The pressure guide does not seem to be accurate, but I own a wonderful tire pressure gauge that covers that.

The Porter-Cable 2HP 6-gallon pancake compressor is a reasonably powerful and reasonably portable air compressor.  I think it's the perfect machine for the somewhat-serious do-it-yourselfer (like me).  I only recently purchased one but I am already sold on pneumatic tools, which the PC 6-gallon compressor operates surprisingly well.  Although many pneumatic tools, such as air hammers, drills, and sanders, consume quite a bit of air (generally in the neighborhood of 5 CFM at 90 PSI), I have found that my PC compressor does just fine with its modest 2.6 CFM at 90 PSI.  Unless you need to operate the tools continuously for long periods, the 6-gallon tank provides sufficient ballast to keep them happily buzzing and spinning at full power. My one complaint is that the motor and compressor are a bit louder than I expected.  Then again, the noise of the compressor is hardly noticeable above the din of an air hammer, so I'm not sure it really matters.
If you enjoy using power tools and you have not yet experienced the pleasures of pneumatic gizmos, you should consider purchasing a small but serious compressor like the PC 2HP 6-gallon pancake.  It's truly amazing how versatile compressed air is; basically any tool that runs on electricity also comes in a pneumatic version (well, except for arc welders).  And, in my admittedly novice opinion, the pneumatic versions have many advantages; they are more durable (with surprisingly few moving parts), often cheaper, and usually more powerful than their electric counterparts.  It makes so much sense to have all your tools share one powerful motor instead of replicating motors endlessly; that is, if you can part with your cordless tools.
But be warned!  If you take the plunge into pneumatic tools, there is an endless stream of items you will find yourself purchasing: air tool lubricants and cleaning kits, in-line oilers, air hoses and gauges, quick connectors, air filters, oil-water separators, Teflon tape, universal air hose joints, air manifolds, blowguns with assorted nozzles, etc.  You'll also find yourself eyeing things like sandblasters and 12-ton jacks, even if you have nothing to blast or lift. (Okay, maybe that's just me.)
One odd thing I've noticed is that the PC 6-gallon compressor is virtually identical to the Craftsman 6-gallon compressor, right down to the paint job.  I'm not sure who copied who, but I can't help thinking that a good design is worth copying.  Either way, the PC version (and presumably the Craftsman as well) is an efficient and mature design.  It's a great way to get acquainted with pneumatic tools.  Get yourself one, and let the fun begin!

Easy to use. Big display that shows the pressure to one tenth of a PSI. No more guessing whether you pressure is under or over the actual pressure like you do with gauges that only display to the whole PSI.

My husband and I found this a lot easier to use than the gauges where a stick pops out.  It has a light on it, and it can be set to read in various measurement units.  We used PSI.  Other than that, just click it on and put it against the airvalve as you would most any pressure reader.

The reading displays on an LED screen that is easy to read.
We just had taken one of our trucks to be serviced the day before, and compared the service record reading on the tires to the readout on the tire gauge.  It was dead on.

We tried it on the other truck as well - 3 different readings were all the same, unlike what I usually get from the kind that pops out.

I like it a lot - its much easier to use than the normal kind.  Its very attractive- I love the deep burgundy color.

It takes button cell batteries that are changed by removing the back- there are 2 tiny recessed screws to remove.

I received a great deal on this pump as part of a promo to get more reviews posted for it. While I haven't put it through thorough use yet, here are my impressions from giving it a try.

The pump works well within the parameters described by the manufacturer. While it's rated to 100 PSI, the instructions state to expect about 85 PSI maximum. This is certainly sufficient to get back on the road after fixing a flat, even with 100 PSI tires. Yeah, they're going to be a bit low, but still inflated enough to get you on your way to someplace with a compressor to top off the tire.

The small size and short-stroke make for a bit of a work-out towards the top end of pressure, but that's to be expected with almost any pump small enough to carry on a bike. On the plus side, this is a double-stroke pump, building pressure on both the pull and push of the handle. The pump seals well over even the smaller-diameter Presta valves, and the pressure gauge is positioned to be easily seen with the valve towards the top of the tire rotation. I wanted to compare the pressure gauge to a calibrated gauge, but have not had the opportunity.

The construction of the pump itself seems pretty solid. The mounting bracket has both clamps the pump securely, and has a peg that fits within a recess on either side of the pump to keep it from extending while you're riding. One of the only negatives I've found so far is that the rubber strap that is supposed to secure the pump into the bracket broke the first time I tried to release it. I've replaced the rubber strap, which can be removed from the mounting bracket easily, with a small Velcro strap. Personally, I prefer the Velcro, as our Southern Arizona summer heat can be brutal on small rubber parts.

All in all, while I've used better mini-pumps on bike rides, I've not used one this good that was in the sub $40 price range. I'd have no hesitation to carrying this pump in my roadside repair kit for long rides along middle-of-nowhere roads.
