Review: Did the trick - I was sceptical that these would work, based on other reviews. They worked for me and enabled me to remove and clean a clogged up aerator, much improving the flow. They aren’t the highest quality and would probably not stand up to regular use. But most people will need them only occasionally and they are fine for that. I just unscrewed the aerator with the tool, cleaned off any obvious deposits, soaked it in limescale remover for a while and put it back. Job done.
Review: Great gadget - Bought to assemble a tap sprayer, needed the key to remove a part on the tap. Easy once had them. Handy little gadget.

This QISF 5-piece cache faucet aerator key set is exactly what I needed for replacing or cleaning faucet aerators. The different sizes (16.5, 18.5, 21.5, 22.5, 24 mm) cover most standard faucets, and the included wrench makes installation and removal easy. The keys feel sturdy and well-made, and they fit snugly without slipping. It saved me a lot of time and frustration compared to trying to remove aerators by hand. Perfect for DIY projects or professional use. Highly recommend for anyone who wants a complete, reliable aerator tool set.
