After testing the Oiktylr Mini Split Cleaning Kit for my 12,000 BTU unit, I can confidently say this is a game-changer for DIY AC maintenance. The PVC bag's thickness (0.3mm) surprised me - no leaks when I blasted coils with my pressure washer!

The included 7.5ft drain hose was perfect for directing dirty water to my floor drain, though I wish it had a clip to secure it to the bag. Pro tip: Use the towel FIRST to catch initial drips - saved my hardwood floors from rusty water stains.

Those 5 brushes? The skinny coil brush reached places my old toothbrush couldn't. But the stiff bristle brush scratched my plastic housing when I got overzealous - gentle pressure works best.

Installation took 3 minutes solo (hooks grip firmly), though my neighbor helped position the bag during final adjustments. After 3 cleanings, the material shows zero wear - no tears despite folding/unfolding.

Cons: The small size barely fits my 37" unit (measure carefully!). Also, the instructional video QR code rubbed off the packaging - had to find it online.

Verdict: At $29.99, this kit pays for itself after 2 cleanings vs. professional service. My AC now runs 15% cooler based on smart thermostat data. Essential for pet owners or allergy sufferers!
