I love my M240! Its so easy to carry around. I take it with me all the time! Throw it in the pickup, jeep, whatever! I frequently air down on jeep trails, so the M240 makes it easy to get aired back up and on the road at the end of the day! It airs up my 33x10.5x16 tires up from 20psi to 45-50psi (depending on how much junk I'm carrying!) In about 2-3 minutes per tire! So about 15 minutes for all 4 then off we go! I wI'll definitely buy another one as gift! Mine has been used alot in the last 2 years and has always worked flawlessly! Cant wait till they get back in stock again!
