Been using this pump on my MTB for pressures up to 50 psi. Works great and the holder given with it is also sturdy and nice.
The product and the servuce by BOTs both great, but their logistics partner delayed it big time.
Works as intended. Initially was a bit hard to figure out how to use it, but after some help from the lovely people at BOTS, was no problem at all.
Element GM-71 Micro Floor Pump with Gauge
So far I've used this twice.
I've used several other mini hand and floor pumps. But this is just effortless and it has a pressure gauge, so its just perfect! You can go up to 100psi in less than 2 mins.
