Great Product
This is a great thing!! I’m going to get my bike in shape & start riding again. Great and convenient for the golf cart tires! Sturdy, compact, & fast!

Very Useful Inflator
I bought my first one and found that it can inflate low tires easily and the battery lasts while sitting in the trunk waiting to do its job. The inflator worked so well I bought another one!

Works perfectly!!
This is a great tool to make sure tire inflation is proper and maintained consistently. Prior to such a device I spent so much more effort keeping them properly inflated, and this just removes all hassle.

Nice seems built good.
Not that fast and battery drains faster than expected.

Quick and Efficient. Powerful little robot.
Perfect in size, doesn’t take up too much space and is far faster and easy than most ways of airing up tires. No need to stop at a gas station, or better yet, you can use it while fueling up your car! Very handy. Speed of device is amazing.

Very nice and calibrated
My husband uses this. You set the tire pressure, and it stops when it gets to the right tire pressure. It had a note with it about the calibration testing. It is made in Spain which is the first thing I remember ever getting from Spain.
