The portable air is AWESOME. It lives up to the hype the advertisements claim. The pump is the reason I give you a 5 Star rating.
The attachments....Not so much. I completely re-plumbed the hoses and the fittings. I would rate the attachments with a SINGLE STAR. Straight out the box the attachments leaked air so bad the pump could not maintain air pressure and the pump ran continuously as a result. I did a test it in the driveway to inflate a tire and the leaky air attachments failed miserably. The pump did what it could do compensate but the air loss was beyond reasonable. I am thankful I wasn't out on a trail. I would have been pissed and we would have had a completely different conversation. The confusing part was the actual hardware itself where the male/female connectors connected together were the reason for the loss of air pressure. At first I thought I had to add more plumbers tape. Nope! That wasn't issue, it was the connections. Were they bad parts? Don't know, Don't care! They are replaced.
I chose to spend the money for a reliable pump. Attachments, they come and go. After I swapped out the attachments this pump performed like a champ. I can not fault the pump for faulty attachments. I am actually planning on adding a larger air tank so I can run air tools while out on the trail.
