I bought the old version and had a chance to test it on trip. Pumps up tires surprisingly fast! Only had a few minutes before the ferry arrived, but it got my front tire from off-road pressure to road pressure in less than a minute. The only thing that would have made it faster and easier would be an integrated gauge of some kind. Has anyone figured out a good solution? I've been thinking of removing the house and making my own with different fittings. Just kinda tedious to air it up above what you need, then deflate with a gauge.
