Time will tell
I’m always weary about how little or how much I spend on wiper blades. Typically wiper blades are a great example of you get what you pay for. When I’m looking to replace blades, though, I’ll often try and see what’s out there before I go spend $25 a piece on wipers. I came across these and they’re highly praised and so I figured why not. I cannot speak on their durability and longevity, but I can comment on my experience with them so far. These are plastic blades. Keep that in mind. They are not heavy or rigid like a metal blade, but also don’t feel super cheap either. The quality of plastic seems adequate for what these things cost. Install is easy, and shouldn’t take more than a few minutes. What I’m very impressed with is how clean of a wipe it makes. They don’t leave anything behind and I haven’t experienced any chatter. I don’t expect these to last as long as premium blades, but I also don’t make gamble purchases like this expecting unrealistic results. If they do happen to have a decent lifespan, then it’s a pleasant surprise and a great value.
