Nice and compact, it fits easily in my jersey pocket and doesn’t threaten to jump out. No gauge and in a 25 mm tire, 200 pumps is not anywhere near enough PSI for reliable inflation. So be prepared to take a break once or twice to get the tire up to pressure. That seems like the major trade off for portability and size. The other reviews criticizing the weight seem unreasonable to me. My food scale weighed it at 5.3 oz, the same weight as 4 scoops of infinit endurance powder (2 water bottles worth) or roughly 2 large mouthfuls if water. Overall satisfied with it and if it lasts like other Silca products have a reputation of lasting, then worth the premium price charged. We will see...
