Things I liked:I like having a spare tank, looks nice with the gage. Things I would have changed:Expensive..!, the gage always indicates 200 pounds less than it should, mine has a rattling noise and shooting is inconsistent. If I go over 5 in the gun's power wheel, the tank releases all the air through the barrel. I'm not happy at all. What others should know:For $200 it should have the 10 for $10 plan option.
