Just got my hands on this 5-piece AC fin cleaning set, and here's my honest take after testing it out.

The variety is impressive - 3 fin combs and 2 brushes. The stainless steel brush is sturdy and does a decent job cleaning between fins, while the plastic whisk brush is surprisingly effective for surface dust.

I had high hopes for the fin combs, but they didn't quite match my unit's fin spacing. The plastic combs are gentle but limited in their application. The metal straightener tool requires patience - it's easy to overdo it and cause more bending if you're not careful.

The brushes are the real stars here. The large white one covers big areas quickly, while the blue detail brush gets into tight spots. They've become my go-to for regular maintenance cleaning.

Important note: This isn't a miracle worker for severely damaged fins. It helps improve airflow on moderately bent fins, but don't expect factory-perfect results. Takes practice to use effectively.

For the price, it's a decent starter kit, but serious fin damage might need professional attention. The brushes alone make it worth keeping in my maintenance toolkit.
