Great for cleaning my soldering iron tip (compared to the sponge that came with the soldering iron). The only downside is the fact that like every other similar product I've found, the metal base of this tip cleaner is incredibly light and needs to be held with the other hand when using it. I plan on adding some lead weights to the base in the near future to fix this, but I don't see why you can't buy one that weighs a few pounds for, say, $20.
