Does the job; may have durability issues

Pros:
  - Nice storage compartments for hose and nozzle attachments
  - Electrical cord and hose not too short, though in most situations you will need an extension cord
  - Electrical cord wraps around base of unit for storage and clips onto itself

Cons:
  - Nozzle has questionable durability--instead of brass, the lining is made of plastic that after only one use was chipped and shedding onto the air valves
  - Gauge only shows increments of 10 psi and has questionable accuracy (it was within 1-2 psi for 3 out of 4 tires but for the 4th my Accu-Gage showed 5 psi higher)
  - Pretty loud but that's probably standard for portable air compressors--I will keep a set of earplugs in the air hose compartment
  - Slow--it took 20 minutes to fill trailer tires 10-12 psi each, but again that's probably standard for a portable compressor and those tires have pretty high volume

Bottom line: if the plastic nozzle holds up, this is a useful tool to save you the hassle of finding a gas station with a working air pump!

Not made very sturdy, but does the job.  For the price, you can't beat it.

Since I've installed this unit almost 3 years ago, this would be a report from the road, so to speak. I'd echo the other reviewers' concerns about strain relief on the signal wires and seemingly cheap feel to the control box. I noted having to be careful about the possibility of pulling out the wires from the printed board when finishing up, and when affixing the box to the wall, the cover kept popping off. The double sided tape against an eggshell painted freshly cleaned wall didn't hold up more than a few weeks, causing the box to start sliding away. Drywall screws did the trick to hold it. Fixing the wires with cable staples might be a good idea for the strain problem. Installation on the plumbing end was fine, though I didn't have the most secure feeling about the quality of the housing for automatic valves. Since I had hammer arresters to put on inline as well, the clearance was a bit tricky on the washer's hookup side, but made it work by rotating the fittings. The sensor and shutoff valve system has worked fine since purchase, and I'm happy with the reliability and security of not being on the hook for water damage to my neighbor's condo below me.

Does the thing, although the plastic is not that flexible.

great item with hopefully long term durability

Does what it says on the tin, however build quality is lacking in some small areas and may not last for more than a few years.

Works as designed.  If you are careful, it will probably last a long time.

Been using for over a month, does its job, no complaints

It'll do the job, but it's not the sturdiest thing I've ever bought.  Can't beat it for the price though.

I purchased one of these belts in March 2016 and the belt has served me pretty well for the past two years. The ratcheting device works reliably and it has withstood roughly two years of almost daily use. However, the pins that hold the buckle to the belt (i.e. where it swivels) will no longer stay in place. I would have expected these parts of the belt to hold up for longer than 2 years, but this is a fairly cheap belt so I can't complain too much. In addition, the belt buckle's finish begins to wear off within the first half year, so the belt doesn't look quite as nice as it does when you first get it. Despite all these failings, I've grown quite fond of the belt and will be purchasing another one. Hopefully it'll last longer than my previous belt.

A reasonable value for something I needed; I'd buy it again if these wear out.

It works as its supposed to and I have had it for a while under serious abuse... drywall dust....sawdust.... metal turnings.  It cleans off, but take a bit of time with a garden hose and makes a mess ( I spray the bulk of the mess into a 5 gal bucket, let it dry and then toss the residue-doo out in the trash).

My less than stellar review is because the blue edge split open and nearly undid my filter.  Maybe it split because it lives in a warm garage or maybe from use, but for the price I was displeased.  I made repairs to it with a staple brad, superglue and some nylon strapping as a reinforcement (it cracked on the outer edge so some additional thickness wouldn't impact it fit onto the vacuum filter support.

Does the job, but after a year or so, it wears down.  I have to replace it more often that I think I should.

This is a nice screen protector. It's clear. It seems scratch resistant. It's easy to clean. I did have a bit of a problem with it, though--and I think it's certainly more inherent to the material (glass) and its necessary thickness than it is any sort of defect. The glass obviously has to be a certain minimum thickness to be durable, but its thickness means the edges do stick up a bit--it's not like some softer, more pliable materials that can be tapered thinner out at the edges (again, it's glass). After a recent trip to Europe, I found the protector's edge chipped in one spot. I hadn't dropped my camera or subjected it to any particularly rough treatment (but I also wasn't being extra careful either--just typical use, the camera dangling from my strap when not shooting). The screen protector is still usable, as the damage is just right at the very edge--but I do have some concern that I'll see more edge-chipping with time.

Gets the job done. I haven't actually dropped it to say whether or not it's effective, but if I do and it doesn't hold up well I will edit my review.

Not top of the line, but does the job for little cost.

Bought this for my home office that is carpeted with basic low pile carpet (the standard builder-grade stuff).  Works perfectly.  No problem with it slipping.  Had it for about a month without any signs of cracks or pits developing, unlike my last (really cheap) one that developed indentations where my chair wheels sat most of the time.  Can't say if it will hold up for the long haul, but it seems like it will continue to do the job. The price/quality ratio made sense for me, and I'm happy with the purchase.

Update:
At about the one-year mark, it started cracking.  I'm still using it, but will have to be replaced one of these days.
