Great experience/Great product.  Purchased at Wal Mart o/a June 2001.  Unfortunately, it quit on me last month.  I was surfing the web looking for a repair video and I came across Amazon selling this.  This has been a great product. Inflating auto and bike tires (getting SUV tires up to specs - about 6 - 10 lbs), basketballs and footballs, had it in the car on road trips for emergency inflation.  Instructions said to charge every 3 - 6 months regardless of use.  I followed that guidance and keep a chart on when I charged it.  That's how I recall having it since June 2001. I may have gotten it earlier but June 2001 is the earliest note I have.  Never keep it running (compressor) longer than 2 - 3 minutes when inflating a tire.  Instructions indicate that if the yellow light comes on during use, to turn it off and charge.  Always followed that rule. Last month after I charged it (o/a April 2013), the yellow light (low) came on when I engaged the compressor, although I'd just unplugged it from charging.  It continues to give me the same symptoms, i.e. after charging the yellow (low) light comes on when I engage the compressor. I figure the compressor is shot but I can't complain.  It's been a great product for the last 12 years.  I forget the purchase price but Campbell Hausfeld is a name I've come to trust for air compressors (I'm a big Craftsman fan but would buy CH over Craftsman air products any day).  Only problem I had was a broken piece of plastic on the door compartment that houses the air hose and attachments (can't recall when it broke but it didn't give me any problems).  Best way to load the AC adapter and cigarette plug is to turn unit up so it sits on the end that houses the air hose and drop the electrical components into their compartment.  I want to get another air compressor and Campbell Hausfeld will be the brand.  I'll probably go for a bigger unit - maybe I can find one w/some attachments, but you can't go wrong w/this model for routine around the house stuff.
