Here is a long steel shaft extender for .580 steel shafts. It has a tapered insertion section at both ends and has a 6 inch middle, so it is able to be used for two extensions (up to 3 inches long each) when cut in half. The long insertion section also helps for better adhesion. The .580 size fits many shafts, including many putter shafts.

These extenders are good extenders. Extenders that don't fit are bad extenders. Aluminum extenders aren't as good as these steel extenders. To conclude, these extenders are good extenders.
