I like mine. Quiet, runs peacefully, and plenty of current for my rig. I have had 6 of these in service at remote radio sites for a bit under three years now, with zero failures or trouble. The fan is automatic, and only turns on when needed. It's a very efficient little supply, and easy to mount.
They run the voltage at around 13.6 all the time, but there is an adjustment on the inside if you don't like that voltage. You have to call the factory to get the location to change it.
