The head is awesome. Magnet to hold the head is maintenance free.
The pump action is a little rougher than i expected but figure it may smooth out with use but some suggestions say to lube the leather plunger. I can see the pump lasting for many years.
I brought this pump based on my previous (10) year experience with a less expensive Silica Pump. My old Silica Pump was so very durable and easy to use. However this pump has a PRESTA ONLY HEAD that is finicky to use in my opinion. To seal properly around a Inner Tubes Valve Stem one needs to insert the stem a prescribed amount (not to little, not too far) and be careful that the Heads Cam Locking Lever does not contacting anything (a spoke or a chain stay or a chain guard or a pannier frame or XYZ) in the fully open or fully closed position or you will have trouble with this Head making a good seal. I think Silica should design a new Presta & Shraeder Valve Friendly Head for this pump that is easier to use.
