Let me start by saying this AC fin cleaner set is a lifesaver for anyone tired of paying hefty service fees. I recently used it on my 10-year-old window unit that was struggling to cool, and the difference was night-and-day!
The 3 fin combs are genius - each fits different fin spacings perfectly. I particularly loved the medium-sized comb (green one) which slid through my unit's fins like butter. The teeth are sturdy enough to straighten bent fins without snapping, though I did find they struggle with completely flattened fins (but honestly, what tool doesn't?).
The two brushes are where this kit shines. The large white brush removed years of dust bunnies in seconds, while the foldable blue brush reached impossible nooks behind the grille. Pro tip: spray some soapy water first - makes cleaning 10x easier!
Warning though: If your AC has ultra-fine fins (like some newer LG models), even the smallest comb might be too big. And yes - quality control seems hit-or-miss based on other reviews (mine arrived complete thankfully).
Real-world results? My electricity bill dropped 15% next month thanks to improved airflow. The air actually feels colder now! For under $20, this set pays for itself quickly. Just don't expect miracles on severely damaged units - but for routine maintenance? Absolute game-changer.
Final verdict: 4.5/5 stars. Missing one star because the plastic brush attachment could be sturdier, and an extra fine comb would make it perfect for all units.
