You paid $14 for the $9.99 grinder? Are you crazy man?
I see you have the newer style, garbage in my mind, that has the plastic bearing holder on the working end, and the fan is ??? well not much of a fan.
I have some older ones that were all metal in the working end, I recently bought another and found that plastic. There were so many other shortcuts over the older models. I am going on quite a lot longer than 5 years on mine. Just had a bunch apart on the back side to shorten the cord.
for $14.99 it owes you nothing, for 9.99 you would be ecstatic and probably thinking I should have bought more.
