I bought this little fella in prep for 100k maint. I had been planning on a 30 gallon portable unit, but this went on sale and I couldn't pass it up. I also couldn't justify the cost and space required for a stationary 60+gal unit when I would never use it's full ability.
It has performed very well. The only time it has had any trouble is when I was using a die grinder with stone to grind off a seat belt anchor rivet. After continuous grinding I would have to stop and let it refill the tank. That was an out of the ordinary task that was outside the scope of what I bought the unit for though. It did get the job done
