### ⭐⭐⭐⭐⭐ replace more often than every 30 years
*by I***R on January 13, 2019*

This kit brought back my ~30 year old Vifa D25AG back to its former self. The old ferrofluid had dried out and was gummy like earwax or worse. Tried using solvent like acetone and OS-10, but that was not super effivient but OK. You don't have to squeeze the fluid out, it gets pulled out in a fine stream from 8mm away, so only a small hole is needed. I used half of the 900ul for two 1" tweeters.
