Not worth buying, 1 month after installation they stopped working well you could see the rubber piece that makes contact with windshield was loose on the verge of coming off, it was put on our 22 civic one that isnt used very often, so the fact that they died out so easily was disapointing, i plan on looking for some better ones and avoiding this brand 👎

Recommend!

These are fantastic. They were inexpensive, which made me nervous, but they are definitely high quality. They were all 3 super easy to install. Highly recommend! They also don't leave my windows streaky.
