Use it mostly on my gravel bike. Mount is secure even on rough roads. Compact enough for how much power you can get out of it. Inflates the low pressure tires really well.
I got this because my high pressure road hand pump just wears you out trying to inflate fat tires. Wanted to see if the high volume thing really made a difference. It does. The pump seems to be well made, the hose and connector work and the rubber handle feels nice in use. The attachment to the bike appears secure and works so far. Nice addition.
Have used it once since purchase. Was able to pump my 32 mm tubeless up to 60 psi. Liked the extending tube which prevents damaging the stem. Liked the ability to screw the pump head onto the valve stem.
Works great. Black matches all bike colors. I carry one of these on both my gravel and MTB
