I have found this pump much better than any I've used before, which have all been hand pumps which you can attach to bikes. I've had it for over a year now and I've not had any issues with it. It pumps up bike tires quickly and with relatively little effort, compared with small hand ones, and I've found it in incredibly useful for my road bike which requires higher pressures. My neighbor borrowed it the other day and was equally impressed. I would definitely recommend it
Love this pump, not an upgrade bit worthy of being for a single bike owner or replacement. Would consider buying another Airtower in time but my only complaint would be having a higher psi and less info on the gauge.
