Don't buy this...
I have tried using it and it would start at the beginning, but when it requires a restart it won't.

Wow...What a scam!
As with most, this unit doesn't play well with others. After one weekend of use it's almost impossible to get the thing running. It seems to have a mind of it's own and it has nothing to do with cold weather, it's usually extremely hot down here. Wish I'd never both the thing.

Compact little compressor, great for my small shop
This little D55166 horizontal compressor is perfect for my small garage shop where space is at a premium. It's oil compressor means it lasts and easily powers my pin and brad nailers. A great product. I know others have really savaged this unit but my question to them is, did they really follow the break-in directions properly? I use Iso 100 synth oil. Works great, I've had zero problems.

nice little portable compressor for light work. i love the handle and wheel on it for moving it. everything is great EXCEPT ONE/2 THINGS: its not for use in freezing temps. it is hard to start up. takes a big jolt of electricity so you cant have weak outlets or it will trip the breaker. ive never been able to get it running in the winter.

So Far so Good
I was nervous after seeing two reviews but took the chance. Dewalt has always performed for me. Had two weeks now, flawless! Recharges quick, portable, works well with NO problems. Somewhat quiet, compared to my old CH. $159 at Lowes and I get a discount. Would recommend and would buy again.

Very good but I recommend to inspect the item when delivered.
Great small air compressor but disappointed about the delivery because the box was open and the tank has a dent on it. Five stars for the product 0 stars for the delivery

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
