Not an inexpensive mini pump, but worth it. No more struggling with hand pumps or guessing whether you have enough (or too much) pressure with CO2 cartridges.
It's small, it's powerful. Other than that it's just nice robust tool to have, nothing special. I don't like how loud it gets so I cannot use it in hotel room when it's late but it's not unique to this kind of pumps. the heat is also tricky but so far I did not melt my TPU so I think it's ok in thermal management unless you really would try to overheat it.
Lots of long time friends said to ditch the frame pumps and CO2, they were correct.
Purchased to take on trip that would require deflating and reinfecting gravel tires for travel as well as for use in the event of flats on the road. It did great inflating gravel tires to desired pressures.
