Breville the Descaler 4 pk

Took about 15 minutes for the powder to fully dissolve and clear the limescale from my kettle, and the water flows perfectly again. No harsh smells during use, which I appreciated.

My espresso machine was pulling weak shots and making a weird noise, so I finally ran this powder through a couple of cycles. The difference is night and day, the limescale is completely gone and the steam wand is back to full pressure. Four packets is plenty for regular upkeep, and the acid formula

These packets dissolved easily in hot water and the acid did a good job breaking down the limescale inside my kettle. A little pricier than generic descalers, but the result was noticeably cleaner.
