Purchased for a friend who is back riding after work with friends on city streets & bike trails. Ease of operation was paramount and the Master Blaster has that in spades. It also mounts easily under the top tube to the bottom bracket. There is a convenient Velcro strap included if you think you need it. She is an interior designer so appearance and construction were a concern. The neutral colors blend/contrast well with her dark blue frame and it appears to be built to last a couple of decades. To sum up this pump does its job very well and looks good too. Even better when you can find it on special at WBW.
Easy to use and moves almost as much air volume as a floor pump but still fits easily into my hydration pack. Thread on head means you don't have to worry about breaking the valve on the tire and you can inflate a 29x2.35 in about 20 strokes. This pump is made for the new plus and fat tires but also works great on standard MTB tires.
I don't know what the guys who wrote the review was taking about when he said threading the hose on would be problematic over time It's all CNC's alloy and seems super durable. I have used other pumps where you slide the whole pump head on the valve and have seen that style break the valve stem clean off while pumping. With this Lezyne pump the hose threads on to the valve and you can pump to your hearts contact without fear of breaking the valve stem off.
Super little pump, does the job and fits into my jersey pocket or use the included clip that mounts under the water bottle cage.
