Total piece of junk. Worked for a while and is a neat concept. Yet hardly a reliable pump which means I never bring it with me. Something with the air rate switch on the back causes the pump to sometimes work or feel disconnected and not work at all. The pump is also super heavy
Pump has worked great. Only reason for 4 stars instead of 5 is pump is difficult to get fully seated on valve at times.
The valve on the back that switches between high and low volume is sketchy. Works sometimes other times it would feel disconnected and not pump any air out the head. When it works its good. I ended up tossing it at the garbage can in frustration. If its not reliable it makes no sense to keep.
