Perfect fit
2015 Honda Fit, does what it’s supposed to. Super easy install. Don’t pay someone $30 to do it at your next oil change. Easy DIY

10/10
Size: 26''+17''+12
I have a 2024 Honda HR-V. It's so difficult finding wipers that work. These were a perfect fit and the price is unbeatable for all 3! Just a heads up- There is a clear film on the blades, I didn't notice and initially thought they were horrible. Once I noticed and removed the film, they work extremely well. 10/10. Will buy again if the price stays this good!
