Easy to use!!

This pump works absolutely great, once you get it to work. Even the gauge seems to be accurate, which in my experience is an absolute first.

It comes with no instructions. I had to figure out what to do with its locking mechanism on You Tube videos. You have to turn the lock lever so it points away from your tire with teh correct attachment attached to your valve. It seems designed to be simple. Only it isn't so easy to figure out how to attach teh valve, nor to turn the lock lever. The lock lever is EXXXTTRREEEEEMELY hard to turn. I'm 67 and I have arthritis. Grow heads and make that lever so someone who is not a professional athlete can even turn it. By the time I got it on my valve and the lever turned I had long since let ALL the air out of my 2/3 full tire, which had been inflated enough to ride to the gas station. AND, I had to kneel on both knees to do this - and I can't kneel on one of my knees. This pump needs ease of use work.

But if you ARE an iron man decathalon champ or whatever, the pump works perfectly. I was eventually able to pump the tire that was by then empty of air in under 40 strokes.

This is a very nice pump that performs well without taking up to much room. This pump replaces an older model that was left outside in the rain.

Finally, a pump that doesn't require me to refit the freakin end onto the valve 15 times before I can actually pump up the tires with a Presta valve! I've had many and so many times it's attatch, remove, attatch, remove, UGH! With this one, it usually works the first time rather than having to refit it 100 times to fill the freakin tire. If you have a bike with Presta, get this pump! I don't know what wizardry they used, but it actually works easily! I now have so much extra time on my hands, I can ride for more than 5 miles!

Great bike pump at a great price.
