I’ve got a Silca. Not sure which model. Got it 3 or 4 years ago, to replace an SKS. Paid less than £100 for it.
To be honest I don’t really rate it.
The gauge is hit and miss.
The tube has pretty much worn through, just from slotting it in and out of the tube holder slot. I’m not a heavy user, just at home etc.
The screw on thing to go on the tyre valve has the habit of bending presta valve pins.
It’s not particularly stable.
Connecting the pump side connector to the valve side connector is not that easy. Brake disks get in the way, esp on smaller wheels.
Wouldn’t get another one, though not looking for a replacement while it still limps along.
