Just a reminder to check those tire pressures often. Yesterday on the interstate I detected a slight wobble in the handlebars. Remembering the death wobble I experienced one time it turned out (again) to be low tire pressure. My air pressure tank gave up the ghost back in June and I've put off replacing it until today. While looking at the new ones I came across this little number with much curiosity. Since I'm not a skilled wrencher, I didn't have a huge demand for my old air tank model so I bought this with the knowledge I could return it if I didn't like it. I did like it! It has built in AC and DC connections, Internal hose and locking chuck plus preselectable pressure amounts and inflation accessories for other items like rafts, balls etc. It's portable and doesn't take up too much room. I've only had it for 2 hours and have already adjusted pressure in 8 auto tires, 4 bicycle tires, my Street Glide and a basketball! lol. If you also need a small light usage unit, I got this at Home Depot, $50 . . . just sayin!
