No, cheap windshields are not worth it. They may seem like a good deal at first, but they can be more expensive in the long run due to their lower quality materials and construction. Cheap windshields are more prone to cracking or shattering when exposed to extreme temperatures or impacts from road debris. This means that you could end up needing to replace your windshield much sooner than if you had invested in a higher quality one. Additionally, poor installation of a cheap windshield can lead to leaks and other issues with the seal around the glass which can cause further damage down the line.
