Query: Great pump for great price

This thing functions great. Topeak may not make the most high quality stuff, but this pump has been outstanding. Solid construction, tight seal at the valve, not difficult to operate. It secures nicely in my bike's old-school frame mounted pump bracket. Has a hi/low pressure option, but it doesn't seem to make a difference either way; that may be because I only pumpy my Arya w/o rims to about 100-105 though. Recommended.
