Topeak has good customers service and their pumps are good pumps but not great pumps. I have a four year old Joe Blow Pro in my garage that has been completely rebuilt twice and I am again having problems with it. A few months back I bought a Lezyne CNC floor pump and it is in a completely different league from the Topeak pump. It is like comparing a Mercedes Benz to a Kia. The Lezyne being the Mercedes. If you ever decide to replace the Joe Blow, take a look at Lezyne. The Joe Blow pump will became a back up pump or maybe I will donate it to a worthy cause.
