I returned Hakko for an EXCESS PRICE that didn't fit my big iron ( B077BLVDHD ), this set fits PERFECTLY on it like it was made for it. As for the Hakko, over $30 for a bent piece of metal, a complete rip off. My iron is also long and the other holders were at a bad angle with the tip touching the plastic or my table, this one lies flatter so the tip is higher. It's durable, but for the worst I can add a heavy magnet to the bottom just for the extra weight. Sponge. like the whole thing just a wee bit of junk but you should still use a copper cleaner not a sponge and if you want a sponge cut a piece off a kitchen sponge. No need to downvote the sponge, they are all junk! Get one of these - THIS IS AWESOME TOO: https://www.amazon.com/gp/product/B005C789EU
