Quality Wipers
Size: Combo Pack (23" & 19"), Style: Top Lock Narrow
These Bosch Aerotwin wipers are a perfect fit for my 2020 Audi Q5 and work exactly as expected. Installation was quick and straightforward, and they snapped right into place with no issues. They wipe smoothly and quietly, leaving the windshield crystal clear even during heavy rain.
Performance feels very close to OEM quality—no streaking, no skipping, just consistent and reliable cleaning. They also hold up well at highway speeds without lifting or making noise.
Overall, a great upgrade or replacement for the Q5. Highly recommend if you want dependable, factory-style performance without paying dealership prices.
