Compressor arrived in good shape. Close to new. Put oil in and ran for 10-15 minutes. Ran smoothly with no problems. Only complaint I have is 2 of the rubber feet were almost halfway warn through. Otherwise no problems.

Really like the air comprresor

Oregon, OH
Very nice compressor. I do finish carpentry, and home re modeling, as well as wood floors and a lot of trim and finish work. I have used pancake compressors a lot in the past, however, I have looked into going to a double stack compressor (double lung as they are refereed too) Do mostly in that they are more efficient. This one is efficient as well as quieter which is a big plus.

Great Falls, MT
This is the second Hitachi 4 gallong air compressor that I have purchased from these fine folks! The products they sell work well for me and the cost are more than reasonable. This tool is compact, nice looking and a very safe air compressor to operate.I would like to say that Bigsky Tool folks are nice to deal with. Will buy more great products here as needed.

Midland, MI
I have purchased several items from Bigsky over the past several years with good results this purchase however did not meet expectations. This is the second EC89 I have purchased from Bigsky; the first one will not run unless the ambient temperature is above 50 degrees F. The current one leaks down so I hope to make one good unit of the two.

Dannemora, NY
I bought this to replace my hot dog style Hitachi compressor that I bought 15 years ago. I am very impressed with the features this compressor has compared to my previous Hitachi compressor. The design is much more stable and the 1/4 turn ball valves for the tank drain is impressive! I will always stand by Hitachi and this compressor is certainly no exception! I would very highly recommend this compressor to anyone who uses their tools frequently and needs to be able to depend on them! Thank you Big Sky!

Punta Gorda, FL
Very well built unit. A little heavy to what I was expecting. Runs fairly quite. Med recovery rate. Very strong unit. No regrets at this time. Perfect for the price.

I was very pleased. The order came within a few days, it was in perfect shape, it was just what I expected. I am a hobbyist woodworker so I have used it a lot yet but when I did it was what I expected. I am now waiting for another reconditioned tool which I will order when it is available.

All I can say is Best Quality for the Best Price ! Looks new, put oil in it & fired it up. Runs like new ! Have not used it much yet, but appears to be a winner.
