New Hakko Tip Day... I can't speak highly enough on the durability of the Hakko brand soldering iron tips. The one on the right is original to my FX-888 soldering station and has lasted 8 years of steady use. Just in the last week or so it has started to finally show it's age with some uneven heating and visible deterioration. So I ordered a new one a few days ago. There are plenty of aftermarket ones that fit this unit but I sprung for a new Hakko branded one. Figured 10 bucks every decade isn't a bad investment.
