  • Excellent portable compressor by FORNAX
Yep, this is a well-built portable compressor. Totally plug and play. Smooth quiet operation sitting on nice rubber feet to absorb vibration. No movement at all while running. It's also very lightweight, easy to carry, has all the right stuff, and no leaks. Plus it looks good. Couldn't be easier. Just don't forget to run it with the drain valve open for 30 minutes on initial start up. It didn't even get warm. Thanks FORNAX. ☺️ ... show more

  • Just follow the instructions and you'll have no trouble with this pump.
Great pump works well little loud.But does the job worth every penny of it. Just the right size, then easy to carry around.

  • OK for Occasional Use.
it's OK... my current std. hoses.. fittings didn't work I had to replace the quick connections (upgrade). Needed 1/4" NPT type M . Not sure what was supposed to connect obut my stuff wouldn't plug into what this came with. This is kinda loud.. but it works and the price was OK for something I won't use a lot. ... show more

  • Very quiet, highly recommend
Amazing little compressor. Takes a bit of time on car tires but that is to be expected. Super awesome on bikes, mowers. Smaller capacity tires, and the most quiet compressor I have ever heard. Highly recommend it

  • Does not hold air longer than an hour.
After 4 months of rare use, tank no longer holds air longer than an hour. I noticed I would hear the compressor come on just sitting in my garage every night. I tested it by filling to the operating pressure and disconnecting the hose and shutting off the compressor. I went out to check it after an hour and it already was down to 0. What a waste of money. ... show more

  • perfect for clearing dust and airing up tires
I use this to top off my tires or after work clearing. it's small, light and tops off quick. it doesn't have much endurance, but it doesn't need it for my needs since I'm just doing 10-15 minute jobs with it.
