I am thoroughly unimpressed with Northern Tool. I just bought a new
compressor from them recently. Before I purchased I called to get some pre-sales technical questions answered. I got incomplete information regarding the compressor drain plumbing as well as some other items and asked that I get an email order confirmation. I was told that I would. I also got a pretty pushy sales job on the Northern Tool Club (or whatever they call it). I did not mind the sales pitch, but after the third time telling the guy that I wasn't interested and he would not give up I was not amused.
After a week with no email I called them back and was told that I would get the email--I still have never gotten it. When the compressor finally arived I could not find the IR start up kit I had ordered and neither could the freight driver. I could not track the shipment contents because I had no order confirmation and this is the first thing you need to track your order.
I also ordered a filter/regulator/lubricator kit and it showed up in a seperate shipment and was in torn up packaging (inside the shipping box). This was so bad that I could not read the torn labels without reassembling the pieces (WTF?)
I found that the IR start up kit had been crushed in the packaging of the compressor. The synthetic oil was ok, but not the filters.
The compressor is installed and works great

, but my purchasing experience with Northern Tool was not good. IMHO, they suck.
